Ok guys, you know my story, I have two of these lil guys, Chiquita is almost 2 years, and Jose is about 4.5 mos, anyways, here is my situation.... They were both raised on Eukanuba, and Chiquita has been on Adult food since earlier this year, and when I got Jose, I had him a separate bowl of puppy food, well they eat each other's food, even in two separate bowls, which are left down at all times to free feed. I am running low on both of their foods, and the ingredients are just about the same, as well as the % of protein, fat, fiber and all that. Would it be alright if I just started Jose on the Adult food early considering its about the same as the puppy food? I'd rather just have one bowl on the floor instead of two, and they eat each others food anyways and both are doing fine health wise. I am also considering switching to Royal Canin foods, and if I do that, I just want to buy the Chihuahua kind, not have to buy the separate puppy formula. Anyone out there like Royal Canin? I've compared Eukanuba's and Royal Canin's %'s and Eukanuba seems to have the higher numbers, what do you guys think?
