Well today after my dog came inside from doing his business I gave him a treat but, when he picked it up from the floor he cried and was unable to chew it.this weekend we're going to orlando,Florida and leaving the dog with a friend.what should I do?:(

Take him to the Vet. He could have as simple as a splinter or as bad as an abscessed tooth. Only a trained professional will be able to determine what it is for sure.

Time for a vet appointment, we can't give you a diagnosis over the internet.
