Max had to have two teeth removed and root canals on two of the big canines when we got him at 4. He is now 10 and a half, and he only has about 13 teeth left - nothing at the back, the four canines, and a rest at the front, a few each side top and bottom. Our dental vet (we go to Fraser Hale as well!) has said that the next time, we might as well pull them all (except for the root canals) - we brush the teeth every day and they are just bad. And since he's getting older, I am more and more reluctant to put him under. He has adapted just fine to living with just a few teeth, I'm sure he will be fine with none.
I'm glad to hear that Karma is doing well at pretty much the same age Max will be when he goes through the same thing! Is he having any trouble adapting??
And I'll just add a "yay" for Dr. Hale as well - great vet, great guy. the set up is awesome; he only sees one patient at a time - his whole team is paying all their attention to your dog. And you get to go back and sit with your pupper as they wake up (which in Max's case, takes a long time - he is slow to come out of anaesthetic, which is another reason for taking them all next time!)
Here's a for Karma - don't worry, it's a soft one!!
