Hey there, I was just wondering if anyone elses corgis roll when playing with other dogs? Mickey loves to herd or be chased by every dog we come across but he quickly warms up to the dogs who play like he does (basically the chasing game, but not too rough) When dogs get right on his heels he developed this little defense of rolling and zooming away. it is pretty funny to watch and he seems to love it. I am wondering if anyone else has experience with this and ALSO is it bad for him to be doing this? Could it hurt his back?
