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).

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.

Finally, a Dog Food My Picky Pup Actually Loves

After trying countless options, I finally found something that works for both of my dogs. I have two Bully Boxer mix puppies one with a dark brindle coat who became

After trying countless options, I finally found something that works for both of my dogs. I have two Bully Boxer mix puppies one with a dark brindle coat who became very ill early on. Since recovering, she became incredibly selective with food. No offense to Cesar, but that was the only brand she’d touch until now. I decided to try this food out of desperation, and to my surprise, she took to it immediately. It was a huge relief to see her not just eat, but genuinely enjoy her meals again. Honestly, switching to this brand was the best decision I could’ve made for her. While the cost can add up (I spend around $9 for a 3 lb bag every two weeks for the brindle pup, and $35 for a 25 lb bag for my other, less picky one), the quality and peace of mind are absolutely worth it. It’s not easy finding something that satisfies both their appetites and my standards but this does.

It's good food for the price but I did switch to the Naturals By Diamond line of dog food because of the difference of ingredients. My Doberman who has a sensitive stomach loves the stuff and definitely gets plenty of energy from it.

How much energy it’s given her to nurse her puppies

It’s been amazing with keeping her coat shinny and most momma dog who are nursing are super skinny right after giving birth because of how much the puppies take
