I personally do not know anything at all about them. I have never been exposed to one or known anybody with one? You do not see many long hair dogs down here in the South because of the heat. I have always heard they are a very intelligent breed, but you have to be careful of the genetics due to popularity, much like golden retrievers. Fill us in guy, what is it like living with collies? My two hounds just went straight from our pond where they were cooling off then jumped on our bed, wife unit is less than pleased with them at the moment! And not happy with me for not toweling them off prior to letting them in! I am in the proverbial doghouse yet again!
