Loss of Appetite

It's no secret dogs enjoy their food. So it's quite distressing when your dog loses interest in food altogether. It can happen for all kinds of reasons.

Common Reasons Dogs Won't Eat


A decreased appetite is usually a sign of sickness, especially if your dog has other symptoms at the same time. Although a loss of appetite in dogs isn't always something serious, it could be a sign of infections, dental disease, pain, liver problems, kidney failure or even cancer. So consult your veterinarian as soon as possible.

New surroundings and travel

Some dogs get nervous and uncomfortable in unfamiliar places - like new homes or on holiday.

Others get travel sickness. If your dog's appetite was fine until you moved or took them on a trip, this might well be the cause.
Picky eaters or behaviour problems
Some dogs are just picky, or won't eat in places they feel uncomfortable, such as around another dog or from a bowl sitting somewhere that makes them uneasy.


Just as vaccination can make us feel off-colour for a day or so, they can do the same in dogs. As a result dogs very occasionally lose their appetite just temporarily, for a day or so.

What Can I Do When My Dog Won't Eat?

If your dog's appetite doesn't resolve within a day or two, seek veterinary advice.
