Polish Lowland Sheepdog Puppy Wanted

Hi, Three weeks ago we had to put to sleep our 13 1/2 year old Golden Retriever. We are seriously thinking about replacing her but not until late spring or early summer June 2011. We cannot have a Golden Retriever again because our daughter-in-law has an allergy to long haired dogs. We would like to know more about the Polish Lowland Sheep Dog and have done some research to date. We would like to know of possible availability of puppies in late spring or early June in southern Ontario, anywhere from Windsor to Ottawa. Thanks Warren and Martha
