if there was only one person who told me their dog had a problem with bones, i wouldnt chance it, I could be giving my dogs their last supper, and I cant for the life of me understand anyone that feeds them knowing they could choke on them, and there is more than enough evidence to support this on the net.
Although animals in the wild feed on rabbits, and in effect raw bones, we have no idea of knowing how many have a problem and die? I dont use rawhide either as I have had to fetch them out of my dogs throat when they try to chew them when theoretically they are too big to swallow.
Hard biscuits and regular dentistry are sufficient to keep dogs teeth cleaned, it just takes more effort on my part as opposed to throwing the dog a bone! - I dont feel the person from Purina is supporting his company by writing about the pitfalls of bones, as we wouldnt expect a dog to live purely on bones and would give them some kind of regular food in addition?
