Hi Helen0362
Please don't think anyone was casting doubt on your decision - it is however quite a drastic procedure to have done and, anyone not seeing the dog physically, may not be able to imagine that it is indeed a requirement for the dog's wellbeing :)
I was asked some time ago to visit our local dog rescue to assess if one of their residents was a variety of my own breed. The dog I was asked to see was not however while there I did see a youngster, probably around 6-8 months of age, which was so badly overshot that the bottom jaw was at least an inch (if not more) shorter than it should have been. This poor little mite was clearly in distress, very thin and in poor coat/condition and unable to close it's mouth properly. It almost certainly would require rapid attention by a specialist in a similar vein to which you describe and, even then, I'm not sufficiently experienced to say it would be successful as far as long term comfort and benefit to the dog was concerned.
Having seen such an alarmingly bad bite I can fully understand why such procedures may require to be done within a very short period of the adult canines coming through :(
I hope your pup's procedure is successful.
Good luck, Teri :)
