This antler is likely to withstand weeks to months before it needs to be replaced. ecommended for: Medium to large adult dogs over 50 lbs who love to chew. Good for customers looking for a very long lasting chew. The heavier the antler, the tougher the chew. Whole antlers are much tougher than split antlers, and deer antlers are much harder and denser compared to elk antlers. Pick the right sized antler depending on the chewing strength of the dog (i.e. a large German shepherd should not be given a small antler, they should be given a large antler). If your dog seems to not be interested in the antler, try to simmer (not boil) them for about 30 minutes in beef broth, to add some flavor.
