It seems that once they get a taste of runnimg, they are hard to cure. We had 2 or 3 dogs loose here for quite a few years, but then they got the urge to roam after some neighbours dogs came to visit when the one female was in heat.
Only thing that works is to keep one tied, so they have to take turns on the end of a doggie cable. We have made the mistake of trusting that loving, "I would never run away again" look in their beautiful brown eyes, only to have an angry neighbour call and say that "your dogs are over here chewing up our cats" or
chasing the deer. . . "
The funniest one was when our next door neighbour called and said that our Great Pyrenes was sitting at her front door and wouldn't let her out of her house. I had to believe her because I could hear our dog's big deep bark over the phone! Man, was the lady upset.
I said, "Anna, just think how secure your house is when you are away at work all day!" She was only mildly amused.
