It never occurred to me to give Lily (shepherd-husky mix) antlers, but she would go bonkers when I pulled in with a deer in the truck. She would jump up and try to look in the bed. When the deer was out, lots of sniffing. I always brought home the heart and liver, which were chopped up for her and the cats. Then, when I picked up the meat, I'd bring her home a box full of deer bones. I'd give her one a day until they were gone. The shoulder blades and smaller stuff, including rib cages, she would eat. She would sometimes eat some of the leg bones, but some were still being chewed on and played with well into the summer.
Lily (14+ years old) died of kidney failure the Saturday before Thanksgiving, not too long after I got my second deer this year. I was incredibly sad to have lost her, but glad she got those last deer treats.
