Opinions please! Operation or not...

Dear Friends,

My almost 14 year old LH chihuahua was found to have a fractured jaw during a dental cleaning visit at the vet. It may be fractured do to natural erosion of the jawbone since he has a missing lower canine and another tooth in that area. It could be a fracture from trauma, or it could be a combo of both. He did take a bad fall off a chair a few weeks ago, poor thing may have broken it then. SO SAD!

Vet said it would heal up in 8 weeks if it was from trauma, she says coyotes heal in the wild, etc. Feed soft food and wait to see what happens. May not heal perfect, but, really does not matter. If it is from natural erosion, not healed in 8 weeks; feed soft food for the rest of his life.

Official reommendation was to go to a specialist, get x-rays (requiring anesthesia)
and probably get a wire and pin to hold bone in place to heal correctly.

Since this little doggy is my whole world, what is the best thing to do? I think maybe get a 2nd opinion, but for some reason the jaw x-rays need the animal to be "knocked out" from what I understand.

He seems very happy and cheerful, even tries to nip the cats, to my dismay. He is eating soft foods and hopefully will gain back some weight. (he lost weight and this was the answer as to why)

AU NATURAL or get x-rays and see what we got? The surgery specialist does operations for a living so I am a little concerned about that opinion!

I am also aware that too much anesthesia too often is hard on the old little guys. He just went under for the dental clean.

Thanks everyone
