A boy and his dog

We are asking for help with rubi surgery.
On Monday afternoon Rubi went missing.  She was found in the neighbor's field in a foot trap. Set legally by a inconsiderate, irresponsible trapper.  Simply informing is that he had k9 traps set would have saved us alot of headache.  That in itself wasnt to awful, luckily she was only caught by her two middle toes. She had been there long enough that she tried nawging the trap off her foot. Resulting in her breaking of 24 of her teeth. We have already spent $320. On emergency vet bill and the surgery is estimated over $3000.  And with the holidays upon us,  this is going to be a hardship on us. 
Theses two are inseparable.  Everywhere the boy goes, rubi is call to go with. "Rubi come" is heard echoing in the house all day long. He won't go outside without her, he won't go in the basement without her. She is his security blanket,  and she needs to be sawn up. 
Please give what you can to help offset the cost. 
Thank you.
