My recommendation is to get a hold on the Whole Dog Journal's (go to their website) annual ranking of dog food. They are an indpendant journal that does a testing of all major commerical dog foods every year. They look for whole foods, no- by products, and a number of other critiera. I buy dog food based on thier rankings and my own research (I've read some books on dog nutrition). I also rotate dog foods because I've come to the beleif that no single dog food can be "complete" and feeding one food for a long time can result in too high levels of some vitamins and minerals while not enough of others. It makes sense. Chicken is a different form of protien than meat. Each animal has a differnet source of nutriants and a different metablism. Natually, nutrition from a chicken product is going to be different(not better or worse, just different) than one from a meat product. Anyhow, here are foods I have given my dogs that both they and I like:
Merrik (dogs love this one but a bit high in fat)
Azmira
Wysong
Solid Gold
Newman's Own Organic
Royal Canin (I find this is a very fatty food so I feed it sparingly)
Pinnicle
Natures Variety
Wellness
Lickthestar has recommended a number of great foods!
I do not feed Eukanuba, Science Diet, IAMS, MIghty Dog, Benefial (or any other Purina product) but I'll let the surveys of Whole Dog Journal explain since it's too long an explanation for a post! lol.
