Linds n' all: I would NEVER put an animal down solely for being aggressive towards others.... My "Larry" thanks that muchly, as the 4ft iggy has biten me seriously twice......my "Sassy" would like nothing better than to get a good CHOMP in ( hog isle boa ). Trust me, an aggressive animal is NOT a reason to euthanise.
Meg, my vet is a local vet and I'm quite happy with him.
Lizzie was not bit whatsoever. Yet she chewed herself. ( When I buried her yesterday, I looked and she had broken the skin and teeth marks apparant ).
I too feel there could have been a medical explaination for her behaviours....However, I do feel quite confident, that said medical issue was terminal. No I'm not a vet, nor a high expert in dragons, but I do know my lizards, the histories etc. as does my vet. Sure I could have broughten her in and subjected her to test after test.....but she showed no signs of letting up on her leg even after I removed it from her mouth
I know you aren't trying to make me feel worse, and I respect your opinions very much so.

Least, you could express your disagreement in a civil/calm manner. Thank you.
All: I think I made several mistakes:
1 big one was posting when upset. Had I been in a more "stable" state, I could have explained more thorough in the first post to save some emotions for those reading.
Two: easily misunderstood wording.
Anyways, what's done is done, no changing it now.
I thank you all for you views, comments, opinions and condolences. Burying Lizzie was the hardest part. Posting about it was the next hardest as I knew I opened myself up to lots of differing opinions. I just wanted people's opinions and to share in hopes that noone else has to go thru anything like this, and if they do, that they can feel comfortable sharing.
Peace.
