I know both PyrShep(I've had 4)and BC(we had a working male),well. I,also,spent a lot of time,in Fl with both Aussies and BC as I was on a flyball team and my neighbour with whom I walked with,nearly everyday has 5 of them and does rescue. In energy level,the PyrShep is higher(his nickname,in Fr is:Mr 100000 volts) than both Aussie and BC. This was confirmed by the BC breeder who does both breeds. I have found 2 great breedersne who breeds beautiful Aussies and the other one who does both BC and PyrShep.Both breeders health test their dogs even if not,always,indicated under the dog's name or in pedigree and show. Had a long talk,with the BC/Pyrshep breeder and really have a good feeling. What do you think of her dogs?: BORDER COLLIE As for the Aussie breeder,I will talk to her,this WE: Berger Australien - elevage du domaine d'arinella bianca I've always had herding breeds and just,want another one. This would not happen until a yr or 2 but DH is thinking of getting a couple of sheep(4 or 5) and I,only,agreed if I could get a herding dog as I'm done running after sheep,like I did when my father had 600+ escape artists.
