My 10-month-old dog is skinny and won't eat dog food. What's wrong?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 10 months and 17 days old | 9 lbs

My dog is 10 mths. He won't eat kibble or can food,we've tried several brands.I even tried mixing fish oil and warm broth. Nothing works. We tried to starve him by not giving him anything but dog food and he still won't eat for few days. At one point he threw up maybe due to gastric acid. He is very skinny. However if we give him dog snacks and treats or papaya he eats those eagerly. The vet here prescribed him cucurma and Lypex for 10 days and still no improvement. Anything else we should try?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Teddy! Since you are describing him as skinny I worry about medical causes for his anorexia. I would deworm him even if the stool is negative and have a stool sample checked. I have blood work ran to check his kidneys. If all the blood work comes back normal I would do a maldigestion/malabsorption profile (B12, folate, TLI, PLI), a bile acid to test liver function and test him for Addison's disease. Then I would ultrasound him to look for enlarged lymph nodes and thickened intestines that would suggest Inflammatory Bowel disease. I hope this helps and I wish you and Teddy the best!
