The big dogs are pretty much free to roam when they are out and she said that Rusty only comes over there to poo! A few times, she will either take him or he will follow her back if she is walking, but he is back over here w/in a few minutes.
I don't think they will ever take him back because they won't keep him in the house, nor have time for him, nor the money to take care of him...so I am really not too worried.
I just thought it was pretty weird (as my daughter says "freaky") and scary that she would just stand or pull into our drive and just sit there w/o coming down to the house.....just crazy!
We will see if she does it again! I hope they move away!
