Meet Blue and the ver that saved his life he is afour year old german shepherd that belongs to my sister sally, two week ago blue suffered a twisted stomer and had my sister not got him to the vets when she did for a life saving operation he would of died, she got him there just in time. The ooeratokn cost. just inder 4,000 for which sally had dog insirance for, however he needed 24 hour round the clock care and this cost my sister 800, she is a pensioner with no savings and had to borrow it with little hope if being able to oay ot back, some mighr say WHY well if yiur an animal lover you will know exactly why. My sister lives her dog and hes her constant companion she would be heartbroken without him so please could we ask for yiur help in raising some if not all what she needs thank you so much for reading this and any help is so gratefully received.
