Whenever I bring a deer home to butcher the dog (Working Cocker)
knows he's in for a treat. All the good bits are for me and Lady Longstrider, but scraps go straight to the dog and anything that doesn't look worth mincing is cubed and cooked before being frozen in small quantities ready to add to his usual fare of tinned and kibble. Never had a problem with him getting the squirts doing this. Liver is too rich for him (the experiment had poor results, as above) so I leave it out of the equation.
Last weekend I finished up the butchering on a fallow and was busy bagging up the meat and noticed that the dog was (most unusually) not by my feet. Turned to see the little $£*^" dragging the remains of the skeleton around the lawn

Roadkill, whether just seen, or those that I've been called out to 'deal with' NEVER gets taken home for us or the dog. We're not so short of feed that we need to take a risk with it.
