I feed Maya a Prey Model Raw Diet. I consider it to be more accurate than the BARF diet as dogs don't actually eat veggies as a main part in their diet in the wild. Wolves shake out the stomach contents of their prey. Everything a dog needs is in the meat. But when you feed a raw diet you HAVE to follow the guidelines or your dog will be missing nutrients. Make sure to feed variety, and feed 80% meat, 10% bone(chicken bones raw are the easiest for dogs to eat, and believe me are completely digestable raw). 10% organ. Half of the organ amount HAS to be liver of some type. the other 50% can be any organ you choose. But note that heart, and I believe brain is considered meat not organ in the raw diet world.
To start you feed 2% of current or potential body weight. More if you have a dog that has a hard time keeping weight on. Maya is 65 lbs and she gets 2.5% or 1.62 lbs of meat/bone/organ per day. I have to say she looks 100 times better than she did before, and I'm finally getting solid poop, which I didn't have until the raw diet. She had really bad allergies as a puppy, until we switched.
ADD: Wellness is a high quality dog food. You can find it at Petco. You can also sometimes find it at smaller pet stores. Smaller family owned pet stores also usually have the higher quality foods like Orijen, Wellness, and Natures Variety, that you cannot find at Petco or Petsmart or for the most part any other large mass producted pet store.
