When a beloved pet dies, the grief that fills your home is not yours alone. If you share your life with more than one animal, you may find yourself watching your surviving pet in the days that follow and wondering: do pets grieve when another pet dies? The honest answer is that most of them do, in their own quiet way. They may not understand death the way we do, but they understand absence. They feel the change in the house. They notice the empty bed, the missing smell, the routines that have shifted. And sometimes, they struggle.

This post is for anyone sitting with that question right now. Whether you recently lost one of your pets or you are preparing for a loss and thinking ahead, we want to help you recognize what grief might look like in the animals you still have at home. And offer some gentle, practical ways to support them through it.

Do Pets Grieve When Another Pet Dies?

Research into animal cognition has made it increasingly clear that many species form genuine social bonds. Dogs and cats especially tend to build their daily lives around the other animals in the household. They sleep near each other, read each other’s body language and develop a kind of companionship that runs deeper than we sometimes give them credit for.

When that companion disappears, surviving pets often show real, measurable changes in behavior. Some of what we see may be a response to our own grief, animals are remarkably sensitive to human emotion and they pick up on our sadness even when we try to hide it. But much of what grieving pets display goes beyond mirroring us. They search. They wait. They stop eating. These are responses to their own loss, not just ours.

Not every pet will grieve visibly. Some seem to adjust without much disruption, which can feel jarring or even guilt-inducing to their owners. That is completely normal too. Just as humans process loss differently, so do animals. There is no single right way for a pet to grieve and the absence of obvious signs does not mean your surviving pet did not care.

What Does Pet Grief Actually Look Like?

The signs of grief in surviving pets tend to be behavioral rather than dramatic. They are easy to overlook, especially when you are deep in your own sadness. Here are some of the most common things families notice:

• Searching behavior. A dog may sniff the spots where their companion used to sleep, or pace through the house looking for them. A cat might wander into rooms they previously avoided or cry at night.
• Changes in appetite. Some pets stop eating or eat significantly less. Others eat more than usual, which may reflect anxiety or a disrupted routine.
• Lethargy and withdrawal. A normally active or social pet may become quieter, sleep more and lose interest in play or interaction.
• Clinginess. Some pets become much more attached to their human family members, following them from room to room and showing signs of anxiety when left alone.
• Vocalization. Dogs may whine or howl more than usual. Cats may vocalize at odd hours or in a way that sounds different from their normal communication.
• Changes in sleep habits. Your pet may avoid the spots they once shared with their companion, or they may seek them out repeatedly.

Most of these behaviors begin to ease within a few weeks. If they persist beyond a month or begin to significantly affect your pet’s health, particularly if they stop eating for more than a day or two, it is worth a call to your veterinarian. Prolonged appetite loss in cats especially can lead to physical complications that need medical attention.

Should You Let Your Pet See the Body?

This is one of the questions we hear most often from families who have chosen at-home pet euthanasia. There is no definitive scientific answer, but many animal behaviorists and veterinarians believe that allowing a surviving pet to briefly approach and sniff the body of their companion can help. The idea is that smell is the primary way animals understand their world. When a companion simply vanishes, there may be no clear signal to the surviving pet that they are gone. A brief, calm opportunity to acknowledge the body can sometimes reduce searching behavior in the days that follow.

Whether or not you allow this is entirely your choice. Some pets show no interest. Others approach calmly and then move away. Follow your surviving pet’s lead and do not force the interaction. If the experience feels too hard for you personally, that matters too. There is no wrong decision here.

Gentle Ways to Help Your Surviving Pet

You cannot explain death to your dog or cat. What you can do is offer consistency, comfort and patience. These are the things that tend to help most:

• Keep routines as stable as possible. Feeding times, walks and play sessions provide structure that is grounding for grieving animals. Even if you are struggling yourself, maintaining those rhythms helps your pet know the world is still predictable.
• Increase gentle interaction. Extra time sitting quietly together, slow walks and calm petting can all ease anxiety. You do not need to do anything elaborate. Presence is often enough.
• Do not rush to remove the companion’s belongings. Their scent on a bed or a toy can actually be comforting to a surviving pet. Let your instincts guide you on timing.
• Engage their mind and body. Gentle enrichment, a new puzzle feeder, a short training session or a different walking route, can help lift a lethargic pet out of a slump without overwhelming them.
• Be patient with regression. A house-trained dog may have accidents. A confident cat may become timid. These setbacks are usually temporary. Respond with patience rather than correction.
• Watch their physical health. Monitor eating, drinking and elimination. Grief is real but it should not be allowed to mask a medical problem that needs attention.

What About Getting Another Pet?

Well-meaning people sometimes suggest getting a new pet quickly to give the surviving animal a companion. This can work beautifully in some situations and go badly in others. A grieving pet who is also anxious or lethargic may not be ready to welcome a newcomer. An older pet who has lived one-on-one with their companion for years may actually prefer a quieter household going forward.

There is no correct timeline. If and when you feel ready, introducing a new animal slowly and thoughtfully gives everyone the best chance. But it is also completely okay to let your surviving pet. And yourself, simply have time to adjust before making that decision.

Grieving Together

One thing that is easy to forget in the middle of all of this is that you are grieving too. Watching your surviving pet mourn can make your own loss feel heavier and more complicated. It can also, strangely, be a comfort. There is something real in knowing that the animal you lost mattered to everyone in the household, not just to you.

If you are in the middle of making an end-of-life decision for one of your pets and wondering how the others will cope, that concern reflects the kind of thoughtfulness that makes you a good caretaker. The surviving pets will look to you for steadiness. You do not have to be perfectly okay to give them that. You just have to show up, keep the routines and let time do the rest.
