vet bills for my dogs broken tooth

Hi, my doberman kaya broke her canine tooth to the point where the nerve is sticking out. She needs root canal treatment then a titanium tooth cap. This will cost over 2500 pounds with the surgery. Fixing this will tooth will get her back to her normal self where she can play tug and fetch a ball. Even £1 will be highly appreciated. I cant put into words how much this dog means so me she’s the best dog i’ve met. She’s only 2, she deserves a chance.
