Help with Vet Bill After Dog Attack

My sweet little Izzy bean was viciously attacked Friday night by a large, aggressive dog being walked by a pet sitter. 

I'm working to get things settled with the dog walker insurance and the owner, but it could be weeks before reimbursement. If that all goes well,  I'll reach out to everyone about paying back.

Izzy was sitting on her favorite ledge under the bushes in my front courtyard when a local dog lunged at her, grabbed her and would not let go as three adults worked to fight him off. After what seemed like an eternity,   he finally let her go but broke her right leg in several places along with a fracture to the sternum.

The vet managed to get her stabilized and she can recover over time, but not until after a full amputation and lots of vet care.

Financially, this is nearly impossible for me to manage. She is my companion who's been with me through so much,  I can't imagine giving up on her.

Your help with these bills is greatly appreciated!
