My 3 dogs (2 Bostons, Simon and Henry, and Willy, an English Mastiff) eat "Merrick" dry kibble (grain free). I mix wet food and a bit of water as they are gobblers. Henry is the picky one of the bunch. He usually will not eat for anyone but me. I decided to try the grain free "Vital" salmon and ocean fish, and also the chicken, egg, beef and spinach. Henry just went nuts! He doesn't care who feeds him now! He can hardly contain himself and starts drooling as soon as he sees the bag! He practically springs to his feet and has the bowl licked clean in a matter of moments! I thought this enthusiasm might wane after a bit. If anything, they are getting more enamored with the stuff. Now to the gross, but necessary! comments. They don't poop as much! I think their bodies are using this food much more efficiently than anything else we have tried! I don't hear their tummies gurgling either! I'm not going to say this isn't expensive, but sooo worth the benefits for my dogs! Thank you!!!
