At 9 months old, I don't believe a puppy food is entirely necessary. There are All Life Stages food that could suffice throughout a dogs life. But I guess I'd rather feed a puppy formula over an adult if I wasn't feeding an ALS.
I'd be curious what food you are feeding and what the main differences are between the puppy and adult formulas... usually they are very similar. Did you go to a different brand, different protein source, etc?
If your baby has a very sensitive tummy, then a sudden switch would definitely cause upset stomach. But most dogs could handle switching from a puppy to adult food within the same brand okay, since they tend to be similar in ingredients, etc. Unless, like I said, it was a totally different brand and protein source and stuff. |
