Yes...I use wild pork now and then and beef liver or even churches fried chicken at times or whatever is handy...
I do put importance and priority in feeding the pups a hog head at the minimum once but try for two or 3 times different times...and dragging a piece of pig hide once or twice so I can get them grab it and not just nip at it....whether it is epigenetics, conditioning or exposing...it doesn't matter...what matters is the end result...
