Do pets grieve?
We don’t know if pets grieve in the same way we do, but many show signs they’re struggling after losing a companion. Some are withdrawn, while others seem restless and lost without their friend. Learn what to look out for and how to help them cope.
The way in which an animal behaves can help give us a good understanding of how they’re feeling. Watching our pets closely and looking for changes to their normal behaviour can tell us more about how they are coping, allowing us to provide them with what they need.

I had two guinea pigs. When one died, the other became very quiet and sat by himself in the corner of the cage. We quickly got him a companion and it completely changed his behaviour.
Do pets know when another pet is dying?
Pets may not understand death like we do, but many respond to our emotions. Dogs in particular can be emotional sponges. Some pets may seem anxious, others unaffected. Knowing what’s normal for your pet helps you spot changes in behaviour and to support them through the loss of a companion.
How can I help my pet through grief?
- Keep their routine steady. Familiar feeding and walk times can be reassuring.
- Offer extra comfort. Give them more attention, play, or quiet time – whatever they seem to need.
- Watch their health. Appetite or behavioural changes can signal distress or illness.
- Try calming support. Your vet may recommend pheromone diffusers or sprays to ease anxiety.
- Speak to your vet. If you’re worried don’t wait: they can help assess what’s going on.
Not all pets will behave differently after the loss of their companion. Some may appear unaffected or even seem brighter after a companion’s death, especially if the previous relationship was strained.
Should I get another pet to keep them company?
Some pets do benefit from a new companion, but it depends on their personality and species.
- Many dogs will benefit from another dog in the family, but may need time and space to adjust before accepting a new friend.
- Cats tend to be more independent and can find a newcomer stressful.
- Small pets, like rabbits and guinea pigs, are deeply social and often form close bonds. “If one dies, the other can find it very hard to cope,” says Sam. A carefully matched new companion can make a big difference.
Only consider a new pet when you feel emotionally ready – for your sake and your pet’s.
