@lauriebasler we adopted our neighbors dog, too . We felt it was a rescue as she was going to send the poor Sheltie to the pound. Gasp! We would walk Perry daily as he was used to it more than we were. Each time, he would try to lead us to his old house across the street.
Finally, one day, I walked him over to his old home. His previous owner had remarried and moved. The house was for sale. I let him sniff around his old back yard til he finally took a peek into the vacant house through the back door. I softly explained his mommy is gone. That this was not his home any longer. I was going to be his new mommy and we were so happy to have him in our house across the street.
Well, do you know? Perry never ever looked towards that house again? He was loyal to us for 10 years until he passed away at age 15 just 2 years ago.
