First, always consult with a holistic vet before making this diet change.
How do I prepare my dog’s digestive system for raw meat?
It can be helpful, but is not required, that you begin feeding your dog digestive enzymes a week or so prior to her first raw meat meal. You can pick up chewable papaya enzymes from New Seasons or Fred Myer and feed them after each meal. Continue the enzymes until the bottle is empty. By that time your dog will most likely have the stomach enzymes needed to digest raw meat.
Help! My dog has diarrhea, constipation or vomiting?
Sometimes this happens. Slow down the transition process and add cooked pumpkin (not pumpkin made for pies because that contains added sugar) to each meal. If you aren’t already, add digestive enzymes after each meal.
