Help with veterinary fees after dog attack

This is Besty shes a 5 year old maltese cross. Shes our much loved pet. Yesterday 13/09/2020 she was attacked by another large dog through no fault of her own. She has extensive damage and had to have an operation as the puncture wonders were very deep. Betsy is a very small friendly doggy who also has addison's disease and takes daily medication and has monthly injections. Addison's disease is a condition where she doesn't produce enough of the hormone to deal with stress. So this ordeal couldn't of happened to a worse dog. We need help to raise funds for on going veterinary treatment which has already costed so much. I havent put a picture up of her current injuries as they are very gruesome but I'm happy to share individually. My children want their fur sister feeling better. My children witnessed the attack and we are very traumatised as a family. Any help would be appreciated. Laura  xx
