I first purchased Vital as training treats for my Finnish Spitz. She loved it so much, I decided to try her on it for meal time. My pup had terrible gas with her other food brand. Since eating Vital, she hasn't passed any gas. With her other brand, she would eat a little, play a little. I'd feel guilty taking her food away unfinished. With Vital, she eats it all in one sitting. Great food! Although expensive, its worth it. I love to see how happy this food makes my pup.
