What to Do the First Week After Losing a Pet

If you’ve just lost a pet, we’re sorry. No matter how you found this guide or what you’re feeling, your emotions are real and valid.

The first week after losing a pet is uniquely difficult. Grief can come in unpredictable waves. Simple tasks may feel impossible, and those around you might not understand the depth of your pain. Amid the sadness, practical matters may also need your attention, even if you’re not ready.

This guide is here to support you. It doesn’t aim to push you through grief or present a checklist, but to show what this first week may bring, how to care for yourself, how to honor your pet meaningfully, how to manage painful thoughts, and how to connect with support when needed. You don’t have to navigate this alone.

Key Takeaways

• Pet loss grief is real and can be as intense as losing a close human. You’re not overreacting.
• The first week typically involves both practical decisions and emotional highs and lows. You don’t have to handle everything at once, and you shouldn’t try.
• Grief affects your body as much as your mind. Fatigue, disrupted sleep, nausea, and changes in appetite are all normal physical responses to loss.
• Intrusive thoughts are a common and well-documented part of acute grief. They don’t mean something is wrong with you, and they tend to lessen over time.
• Talking to someone who understands pet loss, whether a free hotline, a grief counselor, or a supportive community, can make a real difference in how you move through this week.

What Grief Actually Looks Like After Losing a Pet

The grief that follows pet loss is real grief. Not a lesser version of it, not something you should be over in a few days, but the kind that can stop you mid-task, make food taste like nothing, and leave you staring at their empty bed at 11 p.m., not knowing what to do with your hands.

Research confirms this. Pet loss grief has been found to be comparable in intensity to human bereavement. It’s also a form of what researchers call disenfranchised grief, meaning grief that goes unrecognized by society despite being deeply and genuinely felt. This is why some people hear things like “it was just a cat” from well-meaning friends or family. It’s not malicious, but it lands like a dismissal of something that was genuinely significant in your life.

Grief doesn’t follow a schedule in the first week. You might feel numb, then suddenly cry while making coffee. Relief after your pet’s suffering can bring guilt. You might feel fine all day, then fall apart the next morning. All of it is normal. The first week after pet loss is unpredictable, so give yourself permission to feel what’s present without judgment or trying to manage it. That’s one of the most important things you can do right now.

If the people around you don’t fully get it, that’s about the limits of their understanding, not the validity of your loss. The attachment people form with their pets is neurologically and emotionally comparable to the bonds formed with close family members. What you had was real. What you lost was real. Your grief is proportionate.

The Physical Side of Grief in the First Week

Grief doesn’t just live in your feelings. It lives in your body too, and the first week after losing a pet can be physically exhausting in ways that catch people off guard.

Common physical symptoms of grief include fatigue, changes in appetite, disrupted sleep, nausea, headaches, and a general heaviness throughout the body. Bereavement has also been shown to produce measurable physiological changes, including elevated cortisol, altered sleep architecture, and immune system disruption, particularly in the early weeks following a loss.

What this means for you practically: you may not be sleeping well, even when you’re exhausted. You may have no appetite, or you may find yourself eating more than usual to cope. You might feel a tightness in your chest that has no obvious medical cause, or a heaviness in your limbs that makes ordinary movement feel effortful. Your concentration may be poor. Your memory may be patchy. These are not signs that something is wrong with you. They are signs that your nervous system is processing something significant.

Be honest about how you’re physically feeling. Rest when possible, even if you can’t sleep. Eat regularly, even if food isn’t appealing. Drink water. Move gently, like taking a walk, if it helps. Don’t force yourself to keep up your usual pace. Acute grief strains the body, so treat yourself with patience this week.

Practical Decisions to Handle in the First Few Days

The first days after pet loss require some attention to detail, even if you’re not ready. Knowing these small tasks can ease the immediate chaos. None are urgent, and you don’t have to do them alone.

Aftercare arrangements

If you haven’t already made an aftercare decision, cremation and burial are the two most common options. Your veterinarian or a local pet aftercare provider can walk you through what’s available. Most veterinary clinics have existing relationships with cremation services and can coordinate the logistics on your behalf. If your pet passed at home and you’re not ready to make a decision right away, it’s okay to call your vet to find out how much time you have. You don’t need to rush this decision, but you do need to make it within a day or two. Love, Baxter’s directory features vetted, certified aftercare facilities.

Their belongings

There is no right timeline for deciding what to do with your pet’s food, water bowl, bed, or toys. Some people find it comforting to leave everything exactly where it was for a while. Others need to move certain things out of immediate view just to get through the day. Both are valid. Give yourself permission to make temporary decisions right now, knowing you can revisit everything later when you have more capacity.

Medications, records, and loose ends

If your pet was on prescription medication, inform your veterinarian so the records can be closed. Some medicines can be returned or donated. For pet insurance, contact the provider to close the policy. Taking care of these small tasks clears your mental list during grief.

Social notifications

You may need to let certain people know: a dog walker, a boarding facility, a groomer, and a vet specialist. This is a hard set of calls to make, and it’s okay to send an email or a text instead of calling if that’s easier. You don’t owe anyone a detailed explanation. A short message is enough.

Caring for Yourself When Everything Feels Hard

The most important thing you can do for yourself in the first week of pet loss is to lower your expectations of what you’re supposed to be able to do right now. This is not the week to be highly productive. It is the week to keep yourself fed, rested, and connected to the people who make you feel safe.

Eat real meals when you can, even if they’re simple. Sleep as much as your body asks for, and don’t feel guilty about it. If you’ve been close to your pet for years, your daily rhythms were likely tied to theirs in ways you may not have fully noticed until now. Morning walks, feeding schedules, evening routines: all of it was structured around another living being who is no longer here. Restructuring your days takes time, and the absence of those routines can feel disorienting in ways that go beyond sadness. That’s normal.

Be careful about isolating yourself completely. It’s common to want to withdraw when you’re grieving, and you don’t have to socialize on anyone else’s timeline. But staying in contact with at least one or two people who care about you, even through text or a short phone call, can make a meaningful difference in how the week feels.

If you’ve journaled before, this is a good week to return to it. If you weren’t, it may still be worth trying. Writing down what you miss, what you’re grateful for, and what you’re feeling can help externalize thoughts that otherwise circle without landing anywhere useful. You don’t have to write well or write a lot. You just have to write something.

The Love, Baxter blog has a growing library of guides written specifically for people navigating pet loss, covering everything from the immediate aftermath to the longer road of grief. They’re there for you whenever you need them, at whatever stage you’re in.

Ways to Honor Your Pet in the First Week

One of the things that can help in the first week is having somewhere to put the love that has nowhere to go right now. Honoring your pet doesn’t need to be elaborate or permanent at this stage. It just needs to feel true to who they were and who they were to you.

Memorializing activities have been found to be meaningful tools for maintaining a connection with a deceased companion while also helping bereaved owners process their loss. This isn’t about holding on in a way that prevents healing. It’s about honoring something that mattered.

A few things that tend to feel meaningful in the first week:

• Creating a small, simple memorial somewhere in your home, a framed photo, a candle, a flower in a place that was theirs.
• Writing about them. Not for anyone else, just for you. What they looked like. What they sounded like. The specific things only you knew about them.
• Looking through photos or videos. This can be hard and comforting at the same time, and both reactions are okay.
• Telling someone a story about them. Keeping their memory alive in conversation is one of the most natural ways people process loss.
• Doing something they loved one more time. Walking the route you always walked together. Sitting in the spot where they used to curl up. These can feel painful, but they can also feel like a kind of goodbye on your terms.

You don’t need to do all of this. You don’t need to do any of it if it doesn’t feel right. But if you find yourself not knowing what to do with the love that’s still there, putting it somewhere, even in something small, can help.

How to Stay Grounded When Grief Feels Overwhelming

Grief has a way of pulling you out of the present. It sends you back into memories and forward into fears, and the present moment, which is the only place you can actually be, can feel hard to stay in. This is especially true in the first week when the loss is still raw, and your nervous system is working to absorb it.

Staying present doesn’t mean suppressing your grief. It means not letting grief carry you somewhere you don’t want to go right now, like the spiral of “I should have done more” or “I don’t know how I’ll ever feel okay again.” Those thoughts are understandable, but sitting inside them for long periods tends to intensify pain without offering anything useful in return.

A few things that can help you stay grounded day to day during the first week:

• Limit how far forward you let yourself project. You don’t need to figure out how you’ll feel in six months. You just need to get through today.
• Keep a small amount of structure in your day. Wake at a consistent time. Eat at regular intervals. Go outside once if you can. Routine creates a quiet container for grief to move through more safely.
• When you feel overwhelmed, slow down your breathing. Inhale for a count of four, hold for a count of four, exhale for a count of six. This activates the parasympathetic nervous system and can interrupt the physical acceleration of a grief wave.
• Give yourself a small, achievable task each day. Not a full to-do list. Just one thing. Getting through it creates a small anchor of forward movement without pressure.

The goal isn’t to avoid feeling your grief. It’s to stay functional enough to move through it without being swallowed by it. There’s a difference, and it matters.

Rebuilding Your Routine After Pet Loss

One of the quieter griefs inside pet loss is the structural one. Your days were organized around your pet in ways you may not have fully registered until now. Morning feedings. The walk before coffee. The particular rhythm of getting home. The nighttime routine that ended in the same place, with the same weight beside you. When a pet dies, the scaffolding of your day doesn’t just feel different; it feels broken. It disappears in places you weren’t expecting.

In the first week, you don’t need to rebuild anything fully. What helps more right now is just acknowledging that the disorientation you feel isn’t only emotional. It’s also logistical. Your nervous system is looking for cues that used to be there and instead finds their absence. That’s exhausting in a way that’s hard to name, and it’s a completely legitimate part of what you’re dealing with.

What you can do this week is establish a few loose anchors: a consistent wake time, a meal at a regular hour, and something to go outside for, even if only briefly. You’re not trying to replace what was there. You’re just creating enough structure to carry you through the days until you have more capacity to think about what you want your life to look like now. Small, intentional repetitions are enough for the first week.

The longer work of rebuilding after pet loss takes time and intention, and it looks different for everyone. When you’re ready for it, our guide to rebuilding your routine after pet loss walks through this in depth, including how to navigate the specific gaps your pet’s presence used to fill and how to create rhythms that feel sustainable rather than forced.

Understanding Intrusive Thoughts After Pet Loss

Intrusive thoughts are one of the more distressing parts of acute grief that people rarely talk about openly. They’re the unbidden images of your pet’s final moments that appear without warning. The replaying of decisions you made. The sudden flash of “what if I had done something differently?” They arrive at inconvenient times, and they can feel relentless in the first week.

These thoughts are normal. Intrusive thoughts and unbidden mental images of a lost companion are prevalent during bereavement and tend to decrease naturally over time in most individuals. They are your brain’s way of processing something it hasn’t been able to integrate yet. They are not a sign that you did something wrong. They are not a sign that you’re failing to cope. They are a sign that you loved something and lost it.

The worst thing you can do with intrusive thoughts is try to aggressively suppress them. Research on avoidance in grief consistently finds that deliberately pushing away grief-related thoughts tends to intensify them over time rather than reduce them. Instead, try this: when an intrusive thought arises, acknowledge it without engaging with it in depth. “That thought is here. I don’t need to follow it right now.” Then redirect your attention gently toward what’s in front of you. This is not denial. It’s the difference between letting a thought pass through and getting pulled into an extended loop.

If intrusive thoughts are frequent, graphic, or so disruptive that you can’t function in basic ways, that’s worth discussing with a professional. But in the first week of acute grief, some level of intrusive thinking is a completely normal part of what you’re going through.

What to Watch for in Your Surviving Pets

If you have other animals in your household, they are likely aware that something has changed. Pets form attachments to each other, and the loss of a companion animal can affect surviving pets in ways that are both real and measurable.

Approximately 75 percent of surviving dogs and cats exhibit at least one behavioral change following a companion animal’s death, with owners reporting an average of 4 to 5 changes per animal. Common changes include seeking extra attention from you, spending time at the deceased pet’s favorite spots, changes in appetite, altered sleep patterns, and, in cats, increased vocalization.

Most of these changes resolve within a few months as surviving pets adjust. What helps them most is your consistency: keeping their feeding and walking schedules steady, offering extra attention and physical contact, and, if possible, avoiding major household changes during this period. Your surviving pet is reading you closely right now, and your own grief will register with them. This is not something to worry about, but it’s worth knowing.

If a surviving pet stops eating for more than a day or two or shows signs of extreme distress, contact your veterinarian. Most behavioral changes are part of a normal adjustment process, but a visit to the vet can help rule out any underlying health concerns and give you peace of mind.

Where to Find Support After Losing a Pet

One of the hardest parts of pet loss grief is that it often has to be carried without the full support of the people around you. Not because they don’t care, but because they may not understand the depth of what you’re feeling. Finding people who do understand makes a real difference.

If you need to talk to someone right now, free pet loss hotlines are available and staffed by trained professionals in pet bereavement. Love, Baxter has compiled a comprehensive directory of free pet loss support hotlines, including university-based programs and dedicated grief lines available by phone and text. You don’t need to be in crisis to use them. You just need to be in pain, and that’s enough.

If you’re looking for ongoing support, whether that’s a grief counselor who works with pet loss, a peer support community, or a space to talk through what you’re going through at your own pace, the Love, Baxter app connects you with compassionate support specifically designed for pet loss grief. It’s there when you need it, on your timeline, without any pressure to be further along in your grief than you actually are.

Talking about what you’re going through is not a weakness. It’s how grief moves. The people who get through loss most intact are often not the ones who endured it alone, but the ones who found even one or two people to be honest with. Whoever that is, let them in this week.

Getting Through the First Week of Pet Loss

There is no way to do this perfectly in the first week. There is only getting through it. Some days will be harder than others, and the hardest moments will often arrive without warning. That’s the nature of early grief, and it has nothing to do with how well you’re handling things.

What you’re doing by being here, by looking for guidance and trying to understand what you’re going through, is already something. It means you’re paying attention to your own experience. It means you’re not just trying to push through and pretend this doesn’t hurt. That matters.

Your pet knew they were loved. You gave them that, and nothing that happens in the days and weeks ahead changes it. At Love, Baxter, we’re here for you throughout this, not just the first week, but as long as you need us. Take it one day at a time, reach out when you need support, and be as patient with yourself as you would be with someone you love who was going through exactly this.

Frequently Asked Questions About the First Week After Pet Loss

Q: Is it normal to feel as devastated as I do after losing a pet?

Yes, completely. The grief that follows pet loss is real grief, and research consistently confirms that it can be as intense as losing a close human. The human-animal bond is neurologically and emotionally comparable to the bonds we form with family members, which means the loss registers in the brain and body in similar ways. Part of what makes pet loss particularly hard is that it often isn’t recognized as valid grief by the people around you, which can leave you feeling isolated in something enormous. If you’ve heard things like “it was just a dog” or “you can get another one,” those responses reflect a misunderstanding of the bond you had, not the actual weight of your loss. You are not overreacting. You are not being dramatic. You are grieving something that genuinely mattered, and the intensity of your grief is proportionate to the depth of your love. Give yourself permission to grieve fully without comparing it to what you think you “should” be feeling.

Q: How long does grief after pet loss typically last?

There is no universal timeline for grief after pet loss, and you should be skeptical of anyone who offers one. For some people, the most acute phase lasts a few weeks. For others, grief continues in waves for months or longer, particularly around anniversaries, holidays, or moments that were tied to routines shared with their pet. Research on pet bereavement suggests that most people move through the most intense phase of grief within the first few months, but what “moving through it” looks like varies widely from person to person. What matters more than any timeline is whether your grief is allowing you to function in basic ways over time. If grief is not lessening at all after several weeks and is significantly interfering with your ability to work, sleep, eat, or engage in daily life, that’s worth discussing with a mental health professional who has experience with bereavement. But in the first week, there is no expectation of progress. You are just beginning.

Q: What should I do with my pet’s belongings after they die?

There is no right answer or right timeline, and you should give yourself full permission to decide this however it feels survivable rather than correct. Some people need to pack away their pet’s belongings within days because seeing them is too painful. Others keep them in place for weeks or months because the presence of familiar objects offers a kind of comfort. Both responses are completely valid. If other people in your household have different feelings about timing, that’s worth a gentle conversation, but there’s no authority on what the correct approach is. Some people choose to keep one or two meaningful items long-term, like a collar, a favorite toy, or a blanket, and donate or store the rest. Others keep everything for a while and gradually move things as they feel ready. One useful frame: make temporary decisions for now and decide to revisit the permanent ones when you have more capacity. You don’t have to resolve this in the first week.

Q: How do I handle people who don’t understand my grief over my pet?

This is one of the lonelier parts of pet loss, and you are far from alone in experiencing it. Pet loss grief is one of the most common forms of what psychologists call disenfranchised grief, meaning grief that is deeply felt but not widely recognized as socially valid. The people who minimize your loss are usually not trying to be cruel. They likely just haven’t experienced the kind of bond you had with your pet, and their understanding is limited by that. The most protective thing you can do is to stop seeking validation from people who aren’t able to offer it, and to find the people who do understand, whether that’s a close friend who gets it, an online community of people who have been through the same thing, or a pet loss hotline staffed by people specifically trained for this. You don’t owe anyone a defense of your grief. You also don’t need to repeatedly expose yourself to dismissive responses. It’s okay to say “I’m not ready to talk about it” and redirect. Protecting your emotional space in the first week is a legitimate form of self-care.

Q: When should I consider talking to a professional about my pet loss grief?

There’s no threshold you need to reach before reaching out for professional support, and talking to someone sooner rather than later is rarely a mistake. That said, there are specific signs that suggest professional help would be particularly valuable. If your grief is not allowing you to function in basic ways, including eating, sleeping, working, or caring for yourself or dependents, that warrants a conversation with a mental health professional. If you’re experiencing persistent thoughts of harming yourself or not wanting to be here, please reach out to a crisis line immediately. If grief is worsening significantly over time rather than showing any periods of relative stability, that’s also worth professional attention. For many people, pet loss grief is a normal, if painful, process that doesn’t require professional intervention, but for others, it can tip into complicated grief, particularly if the loss was sudden or traumatic, if the pet was a primary source of companionship, or if the loss has triggered unresolved grief from elsewhere in life. The Love, Baxter app can connect you with compassionate support and help you decide whether professional grief counseling is right for you. Starting with a conversation is always okay.
