Please Help Us Pay Our Huge Vet Bill

We are a small volunteer run Bristol based Dog & Cat Rescue and Sanctuary. In our care we have a lot of unhomeable dogs which form our sanctuary side .... these dogs can't be homed for various reasons... some bite.... some have health issues..... some are simply too traumatised.... we've taken in dogs from various rescues in the U.K. Where they had decided to have them killed because they couldn't home them.....some of our sanctuary dogs we simply took in because they had no where else to go.....we also have dogs and cats for homing...... but our vet bills are crippling us.... and we simply can't carry on taking in dogs.... we need to clear our vets bill of over £4600 (this doesn't include Teu's operation to staple her cut pad which is upcoming tomorrow 22/11/17)..... we fundraise so hard and do as much as we can but this is sadly just a begging post.... please please please help us :( xxxx
