Why is my dog pooping less after I mixed milk with his food?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | 2 months and 30 days old | 6.61 lbs

Is it not advisable to mix milk on the dog food? It's what the vet told me and I observed that when i started feeding him that mix food he's only pooped once a day now and i've also researched that its bad for dogs and i'm getting quite worried. It seems like i can't trust the vet anymore. Should i consult a new vet for him?

Thanks for using Petco Pet Education Center, formerly Petcoach! When puppies are being weaned from their mother, you should mix puppy milk (not cow or goats milk) with canned food to get them to eat it. At Brixy's age, he no longer needs milk because he has teeth. After a certain age (usually 2-3 months) puppies cannot digest milk properly. I would transition him to a puppy food (dry food is fine, but you can add puppy canned food if you wish). It is not a problem for him to poop once daily as long as he is eating, drinking, and active and not having vomiting or diarrhea. Good luck and kisses to Brixy!
