By volume, feed 50% meat and 25% vegetables and 25% grain. Vegetables can be chopped and raw preferably or cooked if necessary. If supplementing calcium, use a scale to weigh each batch of food. When instructed by the Doctor, you will add seaweed calcium, essential fatty acid supplementation in the form of fish oil, and possibly a multivitamin.
If your dog or cat has a history of inflammation or digestive problems, please start diet changes gradually. As a rule, start with 25% new diet and 75% old diet for at least a few days. Observe for discomfort, vomiting, diarrhea, or gas. If all looks good, then move to 50% new diet and repeat. Continue on to 75% new diet then 100% new diet. When in doubt, proceed slowly.
This transition to a new diet should occur over a few weeks unless specifically instructed to happen faster by Dr. Landau.
