I feed mine pork with no problems, they've had it cooked but it's usually raw in the form of pork ribs maybe once a week. If you're only giving small amounts of meat as training treats though I would probably use cooked, it's easier to handle when out on walks if nothing else! Small bits of cut up hotdog sausage are good as are small bits of roast chicken or cooked ham etc. There's a recipe for liverbread on the It's A Spring Thing forum if you google it and then go to the 'Willow's Kitchen' section.
