"I have given my dog greenies since she was a puppy. As she had gotten older, I have tried to give her age appropriate treats. She is 12 now and absolutely loves Greenies Senior. She "demands" a greenie senior every night (by pretending she needs to go outside, and then sitting down in front of the cabinet where I store her treats). She is a yellow lab, and as you know labs tend to gain weight as they get older. This is a healthy treat that she not only enjoys, but also helps to keep her fit."
