Science Diet dog food has always been my dog food of choice.  Three little dogs were raised from puppyhood to adulthood on this food.  Rarely a Vet bill except for the normal shots.  Very healthy and beautiful dogs grew up on this food.  However..this last little one who will be 1 year in June, has stopped eating it and won't touch it.  I am not sure why.  I have tried all sorts of ways of fixing it.  I feed both the dry and wet food..in different bowls.  He prefers the cats food to his own and I am at a loss as what to do.  So..reluctantly I am changing.  That being said..I would still highly recommend this dog food as it has served my pets well.  I am now looking for a food that will appeal to my little Yorkie..and so far..nothing but the cats food will do..and he CANNOT have that.  Wish me luck!
