You may be fortunate and have a dog that just loves raw food from the first taste. We recommend you still transition them slowly to avoid any stomach upset from the change. For the others...
Expect resistance: Pets are like children – leave them to decide what they want to eat and they’ll opt for the animal equivalent of burgers, pizza and chocolate every time! If they’ve developed a taste for the artificial flavors in some commercial pet foods you’ll need to wean them off their ‘junk’ food addiction and onto our fresh meat diet.
When your dog is hungry, begin with a small amount of raw along with their current food. Choose only one meat protein in the beginning. Chicken or Turkey is most recommend. Monitor your dog and its stool during this process to make sure the food agrees with them. Stop or limit treats. If everything is good, add more raw food and remove the same amount of their current food each day until you are feeding only raw food. Viola! Your dog is now a raw dog and will begin to show the signs of pure health and a strengthening immune system. If your dog shows any signs of discomfort (vomiting or runny stool) slow the process down. If it persists switch to a different protein. (Some animals have a problem with chicken) Rabbit is mild and a favorite of both cats and dogs. If your dog has been eating only dry kibble it may take a little longer for their body to adjust and some pets will just be wary of any changes. Transitioning your pet requires patience. You may have to choose a low traffic quiet place to feed them in the beginning. Healthy dogs can go without food for a full day so don't give in. Rest assured this is the diet that nature intended for them and they should transition without problems.
Never switch a sick animals food without consulting a veterinarian with significant nutritional training.
