I have been feeding my two dogs Purina Beneful: Healthy Weight for the past year or so and it has been working out well. I finally found a food they both love and look forward to. The especially enjoy it when mixing the dry food with Beneful's meat and veggie entree's.
The only downside is my vet has indicated she is noticing a dogs eating this food are requiring teeth cleanings more often, so it appears to be a bit unhealthy in terms of dental care.
