I know this topic has been discussed before, but haven't seen an answer to my question. Is it possible to have antlers too long to give to the dogs for a chewie? Mike has antlers that are pretty old. Over 10 years old. Never treated with anything, other than dust LOL. Would these be ok to give the dogs? Mike said I could if it was ok being they are so old. Not sure if that really matters or not. Thanks guys.
