At how many months should a small breed puppy transition to dog food?

Answer by RebelStar88Apr 07, 2025
I would say 9 to 12 months. For any breed under 25lbs

is this suitable for large breeds? usually large breed puppies need specific food.

Answer by ChewyAug 06, 2020
Diamond Puppy Formula is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for All Life Stages including growth of large size dogs (70 pound or more as an adult).

Seems Like Decent Quality Dry Kibble

The breeder Max came from feed all her puppies Diamond Puppy so we decided to continue feeding Max this so as not to cause stomach upset if we changed food. Max

The breeder Max came from feed all her puppies Diamond Puppy so we decided to continue feeding Max this so as not to cause stomach upset if we changed food. Max loves the Diamond Puppy and can’t eat it fast enough. Our veterinarian thinks the Diamond Puppy is good enough to keep feeding Max until he’s full grown.

Diamond - All Stages

Our bully had this when younger and he always enjoyed it. No tummy trouble or allergies appearing. Good quality food and kibble is a good size.

Much better!

Much happier with the Diamond Puppy than I was with the new formula of Diamond Performance. The dogs are eating the puppy better than they did Performance.

Love it!

We loved this for our puppy, he just outgrew it so fast and decided he no longer was interested in it. But it was great!
