When our first rescue arrived at our home, he was really, really shy. He quickly set up a routine that, if deviated from, caused problems with his potty training and behavior. He’d avoid us, wouldn’t come at all if called, and even have what we called threshold events. In other words, he acted scared of crossing the doorway threshold to go outside or back inside. Getting him out wasn’t bad as we had a small house and we would herd him towards the door upon which he would lose his fear of the threshold and cross it to go outside to take care of business. Getting him back in was much more work. For the longest time, I’d have to go out the front door, climb the back fence and herd him back to the door to cross the threshold back indoors. This routine took a long time before be would follow our first ever dog, we had her since she was a puppy, out and back in willingly.
