Wolves, and thus dogs, are not exclusively meat eaters. They eat more on a
carcass than just muscle. They receive the majority of their calcium from
the bones of their prey, but also eat the partially-digested plants found in
the animal's intestines. In fact, some carnivores eat that first thing after
a kill. Whatever you do, make sure that your dog is receiving enough calcium
thru plant foods, raw bones, or supplements, otherwise it will develop
skeletal problems over time. Adding calcium will help with the Hershey
squirts. That works with humans too.
