my dog keeps groaning and whimpering
He eat his dinner fine, he's not limping or hurt anywhere that i can see of (i have looked all over him) But he just wont stop groaning and whimpering. He's aslo being quite fiddgety. Only thing i can see is that he has a runny nose, other than that i cant think of anything, He seemed to be fine when i checked his paws and legs. Wouldn't let me open his mouth though.
Any ideas anyone?
