Help With Duma’s Medical Bills

My sister’s greyhound Duma was badly attacked by another dog on New Years Eve. Duma is a 2-year-old retired racing dog and one of the sweetest and friendliest dogs I’ve ever met. She has two large lacerations on her neck that needed to be stitched up and is on a lot of pain meds. She’s recovering but isn’t doing great emotionally. Vet bills are expensive and I want to raise some money to help cover it so my sister can focus on helping Duma recover.
