bettyeane..... my cairn terrier used to do what you are describing......... but it RUINED his training!!!!! after learning that game, if i said come, he wouldnt come and if i physically went to "make" him come then he would run away.... He was an escape artist and got out a few times (the last time he didnt come back) and when i would go hunt him down he would run away from me because he thought we were playing the chase game........ it was horrible, i am deffinatly not teaching toby that game
