My dog won't eat and is getting thin. What food should I switch to?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 5 years old | 20 lbs

My dog is not eating well. How often should I change the brand of his food? Either that or hes become accustomed to my daughter feeding him. Hahaha. He seems thin. I can see his ribs. Is there a brand of food you recommend? He is currently eating Ceaser. Twice day. Sometimes he only eats once and that's with my daughter sitting there with him.

Hi and thanks for posting. You shouldn't need to change the food frequently- in fact doing so can create a very picking and finicky eater. Ceaser's is lower quality food. You might opt for something a little more higher quality such as Purina Pro Plan, Hill's Science diet or Wellness brand formula. However, there are causes for decreased eating such as tooth infections or periodontal disease that can make eating painful. Other causes can include kidney or liver disease, pancreatic diseases, and endocrine disorders among others that can lead to decreased appetite and/or weight loss. I would recommend an exam with your veterinarian soon along with some basic blood work to start to determine if there are any underlying issues. I hope this helps!
