Do Dogs Grieve Other Dogs? What Changes You Might Notice

Dogs do not describe loss in words, so we look for changes in behavior. Common signs include following you more closely, seeming less interested in play, sleeping more, moving more slowly through the day, searching favorite spots of the dog who died, or becoming more reactive to sounds and changes around the home.

Some dogs eat less. Others still eat, but more slowly. A few become restless at night or seem unsettled at times that used to involve the other dog, like walks, meals, or bedtime. These changes can be mild and temporary, or more noticeable when the dogs were strongly bonded.

There is no exact timeline. Some dogs seem different for a few days. Others need several weeks or a few months before their routine and mood feel more familiar again. Research and clinical guidance suggest many grief-like behavior changes improve gradually over the first two to six months, though every dog and household is different.

If your dog is steadily improving, even slowly, that is encouraging. If signs are getting worse, staying intense, or interfering with eating, sleeping, or normal function, it is time to involve your vet.

Keep the day predictable. Feed at the usual times, continue walks if your dog enjoys them, and make space for rest. Gentle enrichment can help, such as sniff walks, food puzzles, short training games, or calm one-on-one time. Try not to overwhelm your dog with too many changes all at once.

Comfort matters, but structure matters too. Offer affection if your dog seeks it. If they want quiet space, let them have that. Avoid punishing clinginess, vocalizing, or searching behavior. Also avoid accidentally reinforcing distress by changing every household rule overnight. A calm, steady routine is often the most supportive thing you can offer.

Some pet parents wonder whether letting a surviving dog see or sniff the body helps. Behavior experts do not agree that this is necessary in every case, but some believe it may help certain dogs process the sudden absence. If this is something you are considering, ask your vet what is practical and appropriate for your situation.

There is no evidence that every dog needs this experience, and there is no reason to feel guilty if it was not possible. Dogs can still adjust with time, support, and routine.

This is an important point. A dog who seems sad may actually be painful, nauseated, dehydrated, or developing a new medical problem. That is especially true in senior dogs, dogs with chronic disease, or dogs who stop eating. Because grief and illness can look similar, your vet should evaluate any major change in appetite, energy, breathing, mobility, or bathroom habits.

See your vet immediately if your dog has trouble breathing, collapses, cries out in pain, cannot keep food or water down, has pale gums, or refuses food for more than a day.

Usually, it is best not to rush. A new dog changes the household again, and that can be stressful for both you and your surviving dog. Some families eventually find that another dog is a good fit. Others need more time. Neither choice is wrong.

If you are considering another dog, think about your surviving dog's age, health, social style, and energy level, along with your own grief. Your vet can help you think through whether now is the right time.
