your local vets are a waist of time and money,i use a vet in leistershire if that how u spell it,he was called dennis breary but he went back to ireland,i still use the same place but forgot vets name lol,if its a knock the dogs had or anything other than a wound i go see robert meek hes saved me more money than i care to remember and he also sorted a dog out for me that a local vet said would never run again
