Dog concern
Petconcern posted:
I have a super skinny dog that just won't put on weight. Could eat forever if allowed. He has had a stool test and that came back fine. Anything else to try? He is a black lab. Appears to be healthy but just not looking good and wondered if there was something else to check into.

Have you had your dog's thyroid levels tested? Hyperthyroidism (overactive thyroid) can cause weight loss, excessive hunger, and make your dog feel icky. Your veterinarian can perform a blood test to check.

Hi Petconcern,

Admittedly, I know more about cats than dogs. But my understanding is that Hyperthyroidism (high thyroid hormone) is uncommon in dogs but very common in cats ... and, conversely, dogs commonly get hypothyroidism (low thyroid hormone), whereas that is rare in cats. So, I might look for other things first.

The short answer is that your vet needs to do more testing to see what is going on ... or, refer you to a specialist (e.g. veterinary Internist). I'm not a vet or tech and can only guess ... but I would wonder if there is an intestinal problem, or maybe insufficient pancreatic enzymes, etc that is causing your dog to not digest or absorb nutrients from food properly. Unfortunately, I think cancer can also sometimes cause an increase in appetite while causing weight loss. But I'm sure there are many other medical possibilities that your vet would know.

Good luck. Let us know how it goes.

Information from the Russell Rescue website:

"A stool culture finally revealed the reason for Romeo's health problems. He is suffering from Exocrine Pancreatic Insufficiency (Maldigestion Disorder) which is a disease that affect the ability of the pancreas to produce the various enzymes that allow humans, dogs, and cats to digest their food. Without treatment the dog literally starves to death even though it may be constantly eating."

This may sound scary, but it can be treated. I know you said the stool sample your vet took came back fine, but you might ask what the vet was testing for. Loads of luck to you and your labby, and let us know how things go.

we had a heeler that wouldnt put on weight and our vet suggested adding a high fat cottage cheese to her food. she put on weight instantly and has been able to maintain the healthy weight without cottage cheese. sometimes they just need a little fat boost i think. but i would definitly rule out any issues with blood work first! hope all is well!
