i read the site and it looks like to me thats someones opinion of RAW. you have to be able to distinguish someones opinion vs the true facts. dogs have been eating RAW forever. dogs in the wild have to survive somehow and its in their nature to eat RAW. as long as a dog is supervised while eating a RAW bone its fine.
as for your vet goes most vets are not told much about a dogs diet while in vet shcool. vets are always going to agre with kibble bc they make money off of kibble. (example:science diet)
some may agree with RAW some wont its personal opinion.
