Diamond is the best dogfood we have ever had for our mixed breed dog Bonita. Bonita is about 9 years old and weighs about 40 pounds. Since we switched to this food, her coat is bright and shiny, and she maintains her weight with less food. Diamond is more expensive but is well worth the price.
(FYI...Animal control picked Bonita up as a pregnant stray and she had 4 pups. Her pups were quickly adopted but Bonita was not for over 5 months. We adopted her and she is one of the most intelligent dogs we ever had.)
