my patterdale got run over by a car when she was 6..took her streight to vet and they re located it..we braught her home to lay her in front of fire and before we had time to blink, shed wriggled outa the old mans arms and tryd to run to the other terrier, unfortunatley unlodging her leg from the hip streight away again...back to the vet, re located for second time, hadnt left the surgery....out again, the bitch wouldnt stay still..vet said the only thing for it was this toggle surgery...cost us 750 in all, but shes 15 now and still with us, slowed her right down after the op but worth every p
