Why is my 4-month-old puppy not eating but acting normal and playing?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 4 months and 19 days old | 7.6 lbs

My 4 month old puppy (mini poodle mix) is barely eating the last couple days. He's been eating three meals a day, but now he will make one bowl last all day. His poop has been normal, but it was small and light colored tonight. He is acting normal and still playing as usual. We live in an apartment and he does not go outside. He got the last of his puppy shots this week as well.

I'm sorry Brady isn't doing well at the moment! One possible cause of his eating issues is teething. He is at the right age to have teeth come in, and that will be painful to him causing him to not want to eat. I would try soaking his dry food in gently warmed water or low sodium beef and chicken broth. This will make his food softer and easier for him to eat. I would also recommend getting toys from a pet store that you can put in the freezer before giving it to him. The cold will be soothing on Brady's gums and it will allow him to chew on something hard which is helpful when teething. Also make sure he is up to date on his deworming treatments, as that can lead to a loss in appetite. If he still isn't eating much in the next 48 hours after trying the home remedies I suggested, I recommend taking him into the vet for a health check. Good luck, I hope this helps!
