Large Breed Puppy Food

My puppy is getting bored with her Eukanuba, she LOVES the smell of my adults James Wellbeloved, but I would like to put her on it but they do not do a Large Breed puppy food. How important is this? Has anyone raised a large breed pup on this food? Been comparing the protein etc., and it doesnt vary alot from some large breed pup foods. Can anyone help?

Hi Streetmutt, I have raised 2 GSD's on James wellbeloved puppy food with no problems, hope this helps.

Thats good to know, I was just so worried about growing problems Ruby is a Bullmastiff. But have been told it is sometimes more to do with exercise than diet? Do you still feed JWB?
