We have been using it for a short period of time, but it seems to fit my dog just fine. Despite being a picky eater, he hasn't gotten bored of it so far, and his bowel movements, coat, and mood are as they should be. It seems to have also helped with his allergies. Its price is a bit high, but few foods have so many additives (taurine, carnitine, glucosamine, chondroitin, probiotic, etc.)

The best thing about it is that it contains glucosamine for the joints, connective tissues, and its strength. I have seen a great difference in my dog's legs! It is true that you get what you pay for...
