Jackson was eating adult food by 9 months, and all life stages food for most of his life before that (except he ate pup food when I first brought him home, etc, for the first month probably).
I don't think it's all that important, especially in smaller breeds who are usually typically *almost* full grown by 9 months, and for the most part think specific formulas are a big marketing ploy. The main thing you have to look out for in large breed pups is the calcium and phosphorus but w/ smaller breeds, it's not as big of an issue.
If you compare puppy food with most adult foods, the formulas really aren't THAT much different....
If you want both your dogs eating the same food, I'd buy an all life stages food. |
