Hello,My family is based near York in England. We are looking to get our first Cavalier puppy and are aware of the health issues and the need to buy only from a reputable Breeder. Would anyone know of a reputable Breeder who may have health tested male cavaliers (within 3 hours car travel time from Yorkshire) of around 8-10 weeks of age.. Preferably a Blenheim, Ruby or Tri-colour. Many thanks for any advice that anyone can give.
