dog fud

I have a big dog, who has been eating Wellness Core, and a little dog, who has been eating Newmans Own, which, I learn from that review site, is not actually a very good dog food. I get both dog foods delivered by Amazon Subscribe&Save. Last month Amazon couldn't get any Newmans Own, so I have been mixing some Wellness Core into the little dog's food to stretch it out. This month, Amazon does have Newmans again, but at $35.11 for the 12.5-lb bag that they charged me $20.32 for, last shipment.

I've been feeding them different foods because I assumed that the little dog, who is really very little, needed a smaller kibble size. But he is eating the big dog's kibble just fine. Is there any reason not to feed them both the same (better quality) food?
