Dog ate chocolate?

ask a vet

Puppy doesn't want to eat.

Species: Dog
Breed: Shetland Sheepdog
Age: 6-12 months
It has been over a week since my Sheltie has lost her appetite. She hardly touches her meals and doesn't show any enthusiasm when I give her treats. She is also pooping very little and has bad breath. I have been giving her a herbal digestive syrup recommended by her vet but it doesn't seem to help. What should I do?

Oh dear, it sounds like Spookie is really not doing well.

I always get concerned when a young dog does not want to eat. It almost always is a sign of a medical problem.

There are a number of things that could cause a puppy to not want to eat:


  • Parvo virus - This would be most common in an unvaccinated puppy. The period of not eating and lethargy would soon be followed by diarrhea and vomiting.

  • Ingestion of a foreign object - although usually we would see vomiting.

  • Pain of some sort - Is there any chance she was in an accident?

  • Ingestion of something toxic to her kidneys. This could cause the bad breath as well.


Puppies don't have a lot of reserves to fight dehydration, so if a pup is not eating for more than 24-48 hours then I always recommend blood tests and possible IV fluids if your vet feels she is dehydrated.

I really hope she is ok!

Dr. Marie.
