Hi I have a dog with gingivitis and he is going to go and get his teeth cleaned for it. i now him very well and he does not really ever show his pain. but i fill bad for him, I think he might be in pain but im not sure, is there anything to give him for the pain, but first how do I know if he is even in pain I dont want to just give something to him if he does not need it. So how would I tell that he is in pain. He eats and he drinks. But it sometimes gets hard for him to eat hard food so I have to give him wet food, I just want to know if there is anything I can help him with. Thanks
