Hi I have a dog that has gingivitis and I want to take him for a teeth cleaning next mouth that's the next time they do it and his breath is very bad his teeth are getting pretty bad two teeth you can see under the gum I did not really know he had gingivitis but when started to see the signs I took him to the vet and when I look at his teeth he's paws at me and does not like it but he does not like his paws being touched ether so I was wondering what are the signs of a dogs mouth hurting. Thanks. Oh and here he is his name is einstein
