Some vets are supportive, some not so much. It depends on their background and what they've been taught in canine nutrition class. One vet told me it was, bad, the next told me to cook the meat (really bad advice with bones in tact) and the last vet I talked to only had concerns about a clean cooking environment for raw feeders that might have kids and such. Many go on about puncture injuries, which are certainly possible, but none could actually claim to ever having seen one personally.
One of the sites details a lot about disspelling myths of raw feeding, and why vets, many whom have only had a few hours total education on canine nutrition, have the opinions they do.
Most people I associate with in my dog friend circle feed raw, and have been for years. These dogs are all in great shape, can chase sheep all damn day and still have energy to play some fetch after dinner.
There are lots of benefits, some risks, to you and/or your dog, and doing lots of research will let you make a choice that is right for your animals.
Oh, found the myths link, give that one a read
