Burger, I like your idea but we are talking about animals who can lick their butt and not die from it. Most commercial meat is cleaner than... Well you know! LOL! With a stomach ph of close to 1 bacteria typically doesn't stand a chance of survival and if it does, from nose to tail a raw meal takes 6-8 hours in dogs. Unlike the 12-24 in us. That is why we are much more susceptible to food born pathogens.
All of you feeding wild fish or game PLEASE freeze it for 30 days first. There are some nasty buggers that can make your dog pretty sick. Freezing kills them.
Remind me you to tell the story of my friend Wendy, the free deer, and the red tapeworms. That free deer ended up costing her about $1500.
