If you are unable to walk or train or exercise your herd dog... please don't get one. Please don't yell at your beautiful border collies who have been at your mercy since they were pups. They only want to do a job and because you have not given them one, today it is play with the red head's corgi. Do not ruin everyone else's time at the park by screaming at your dog constantly because it won't come to you. Perhaps this was the wrong dog for you. Next time get a small toy breed :(
If you are wondering, once we got to the otherside of the park we found new dogs to play with that had normal owners.
