I'll be able to get my hands on wild game & the only part I'll be refusing is the brain, as I believe it's Deer brains that are bad for dogs.. I can't remember why, but it has too much of something in it... I also can't remember if its safe for humans either. Glad fish heads are good, cause I get my fish whole (guts n all)... Now I just need to know if eating fish guts raw is safe? or if there is any harm in not feeding them to Digi... If the fish is wild caught then I'm sure there wont be any beef in the gut... but if the fish is farmed, then there is a higher chance the fish have beef in their digestive tract somewhere.
