Bone loss? In a 4 year old? How odd. Maybe they're talking loss from the neck of the teeth, also known as "neck lesions" or resorptive lesions. There's a fancier term for it, but I've forgotten it. If it's tooth issues like this, and the jaw bone is normal, yes, that's vaccine caused.
Some of the comments on earlier posts revealed some "under the radar" means to stay out of harm's way. Just drop the word "rabies" in the search box on any page, and it'll bring up every post and page I've written on the subject. Read the post comments for some creative ideas. Main thing I've recommended: don't start licensing. If you're "in the system," it's harder to get out later, once you've learned your animals are immune long term.
Best of luck Tracy, and we're glad you're here, doing good things for your Westie!
