I use the Wellness Super5 Adult, Small Bites.
My Male Sneakers has been on it for over two years, and
My Female Becca (now 10 mo), was given Puppy, but
she wouldn't eat it, and ate the Wellness Adult since she
was 3 months old. lol
I tried everything at first, cheep to expensive, one, two and
three times a day, NOTHING worked !
I finally just gave up, left the food out 24/7.
Now they both eat together, twice a day, one takes a
bite, backs up, lets the other in, politest two dogs I've
ever seen, and are doing just fine on their own.
Without me getting in their way.
They seem to enjoy eating when we do, and given that I'm
retired, with them 24/7 (just about), I can see that both are
eating (according to their size differences) just about what
they're supposed to.
