I have never seen a dog get intestinal blockage from a rawhide. I am sure it can happen but I have never ever rinsed something off and said yep it is a rawhide. I have seen underwear (seems to be the #1 choice), socks, cat toys (mice), rope toys, string, carpet, woodchips, that meat netting, ornament. I think the one that sticks out the most is the GSP who swallowed a giant size Kong toy whole. I have seen numerous dogs chip their upper 4th premolar (carnasal tooth) on antlers, raw bones (generally the big weight bearing bones). I have seen dogs get diarrhea after gnawing on a smoked bone. I have seen dogs get so impacted because they have had way too much bone that the dog had to be sedated and the impaction removed. I have seen dogs get the bone stuck on the lower canines of the mouth and the dog had to be sedated and the bone cut in order to remove the bone from the teeth. With rawhides it seems to be more of the chips that the dogs get all soggy and try to swallow. This is where the big problem with rawhides seems to be.
I think anything you give your dog could pose a danger and the dog should be monitored during the time it is playing with anything. I have seen something as simple as a towel given to a dog to lay on in its cage kill a dog.
