Allright so i am new to this forum so hello to all, i am posting because my three year old pit bull terrier, i think he is a goddie pit is what i have been told well i fed him a bone and after wards he seems to be having a hard time closing his jaw. He opens it and grinds his teeth closing it. He dose have his bottom teeth infornt i beleive its an over bite. anyways so i checked his mouth no bone on top or stuck i felt down his air pipe and then gaged him to make sure he did not have any bone logeed in his throte. nothing so should i worry it sounds bad his teeth grinding like that but he seems fine when he chilling. I looked online for anything and came up short so i would appriciate the input.
