yes perky is a JACK russle terrier, she has a long back and short legs, person russle terriers on the other hand have long legs, short backs and are taller. its basicly the same as the border collie and barbie collie(not an official name) border collie people dont want the breed ruined by show people, just liek the jack people dont want their breed ruined, so we give them seperate names to diffrentiate betwwen the 2. parson russle=short back, long legs, tall./barbie collie=short legs, fluffy coat,short muzzle, bulky body, just as jack russle=short legs, long back, sturdy build/border collie=long muzzle,light frame,smooth, or long flat coat, long legs.
basicly they are bred for working ability, health, practiblity, where as a parson/barbie are bred soley for looks
make any sence at all?
