We have ours trained to help skin, still working on the gutting part. They have trouble with that whole holding the knife thing.
Very smart dogs. As for that holding the kife thing, it's hard to see from the picture but you didn't have their dew claws removed by any chance did you? The dew claws are basically their thumbs so, yeah, if you had them removed I highly doubt they will ever be able to hold a knife with any sort of proficiency.
EW EW EW EW EW EW EW EW EW!!!!!
Goofy beagles!
