Help Cozmo Recover from Emergency Surgery

Hello, this morning our pup Cozmo got in a fight with his brother Gator. As a result, Cozmo got pretty severely hurt. He is currently having surgery, getting his right ear over half removed, with potentially losing all of his ear. This surgery, being an emergency and over the weekend, is pretty expensive and we are asking for any help to pay for his surgery. We are a humble family living paycheck to paycheck, and this sets us back quite significantly. Anything would help. Thank you in advance.
