My dog won't eat his food. What should I do if my dog stops eating?

Updated on September 23rd, 2025

Pet's info: Dog | Miniature Poodle | Male | unneutered | 7 months and 16 days old | 12 lbs

My dog recently started eating very little to no food. We started switching over his food but then he refused to eat the old food so we stopped tryning to feed it to him. He was loving the new food but then a family member that has been in town for 2 weeks left and he stopped eating. He seems to be acting the same but now he won’t eat the new or the old food. I’m not sure what to do! I also called my vet, but the vet isn’t in yet.

Thank you for sending your question and the photo of Oakley - he is very cute! Sometimes when our pets suddenly change a behavior, we are (naturally) inclined to look at other evernts to see if there might be a connection. While dogs do mourn the loss of people they are very close to, this typically happens when dogs and their people have lived together for many years, so I’m not sure this is a realistic cause of his sudden loss of appetite. There are just so many things that can cause a normal young dog to stop eating - parasites, a blockage in the intestines, infectious diseases like parvo or leptospirosis- it’s hard to say what is going on, but your instincts to go to Oakley’s vet are 100% correct. I encourage you to get him in and get him checked out - exam and blood work at minimum - to see what’s going on.
