Hill's Science Diet Oral Care Chicken, Rice & Barley Dry Dog Food, 28.5lb Bag

My dogs have been eating this food for two weeks. I can see that tartar is disappearing from their teeth. It does what it says. I do wish they would offer same food in smaller pieces because two of my dogs are really small, and the 13 year old has to work extra hard it seems at chewing up the food so I worry she might not get enough to eat since she is eating so slow. I do see it cleaning their teeth very well though, tartar is almost all gone. I have a 4 year old pom, a 4 year old collie mix and a 13 year old pekingese. They all eat it, all their teeth are improving. Like I said, just wish they would offer a small dog version, pieces about half this size would be nice, maybe mix in some other small pieces of regular food so I could be sure my older dog is getting enough food because she is working awful hard to chew this up (she has good teeth, no lack of teeth and no weak teeth or broken teeth or anything like that). Before I bought this my dogs were eating the sensitive skin and stomach science diet.
