This antler is likely to withstand weeks to months before it needs to be replaced. It is recommended for small to medium sized adult dogs under 30 lbs who love to chew. Good for customers looking for a very long lasting chew. Whole antlers are much tougher than split 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). Deer antlers are much harder and denser compared to elk antlers.
