oops.... pressed enter too soon.....
I do use Blue brand for my cat.
Sometime ago I bought the regular small dog food before but she didn't care for it.
I have had issues with my cat not eating some bags of Blue and realizing they were near the expiration date. That could have happened with the dog food.
I see there is a weight management for small dogs with condrotin and glucosamine. I may try it.
Incidentally, Hills Science for small dogs (doxie on the bag) doesn't include condrotin and glucosamine. I wonder why?
