The benefit of meat for dogs is protein not enzyme. Secondly, cooking the meat makes it much more digestible as raw meat has indigestible collagen proteins. In the wild, mother dogs eat the meat from a kill and regurgitate for their pups - serving predigested meat. In addition, raw meat is very high in fat. Thousands of dogs die every year from Pancreatitis, and some are disabled by this disorder after being fed a raw meat diet for a short time. Not only is raw meat high in fat, but the pancreas is made to produce enzymes. Supplementing with too many live enzymes can cause the pancreas to shut down. If your dog has Pancreatitis and you aren't aware of it – a high fat diet of raw meat could kill them.
