My 6-week-old puppy won't drink formula. What should I feed him?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | unneutered | 1 month and 16 days old | 1.5 lbs

I just received Onyx as a birthday gift. I was told he was a 6 week old chihuahua/Maltese mix. I’ve tried weighing him the best I could and he is 1 lb 7oz. I TRY to feed him puppy formula through a bottle and collapsible bowl. He doesn’t really drink too much and I’m worried he isn’t drinking enough. I don’t want to try and feed him anything else until I take him to the vet in 2 days. I’ve noticed he does drink more if I pour the milk into my palm. How much should I be feeding him?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Onyx is adorable!

At 6 weeks old he can eat puppy food. I know you want to wait but it sounds as though he might not be getting enough nutrition and doesn’t want a bottle which indicates he is weaned. I would get canned puppy food and mix the puppy formula in to it. Feed small frequent meals, 3-4 times per day. I like Purina Proplan, Royal Canin, Iams, and Hill’s Science diet.

Good luck
