I have a ten week old pitt I think he swallowed a small raw hide bone. What should I do?

Well Milk bones and raw hides are totally different. If it is a raw hide, make sure watch him very closely make sure he is eating and drinking normally and most importantly make sure his stools are all normal. They should be firm and roundish. If he starts retching and is unable to bring anything up you should contact your vet as soon as possible.
