Sasha is on a restricted protein diet to rule out food allergies. She does well on deer meat and hunter has given us a bunch of frozen meat from last season. There is lots of sausage meat, deer mixed with pork and a bit of seasoning. Are there herbs or spices that I should avoid giving my dog? Normally I wouldn't add any seasoning to her meat, of course, but I do add olive oil to venison because its so lean.
