I KNOW what would work (barbed wire, electic fences, mine fields, etc.) but my problem is a solution that doesn't involve massive cash outlays! We have to pay for college tuition and a trip to Europe for my daughter.
Tomorrow, I am going to the pet store to buy a stake and a CHOKE COLLAR!
I have never wanted to use a choke collar, but this dog is going to get killed, or cause someone else to be killed, if I do not get her under control. And I do not want to have to put her down. I couldn't live with that, let me tell you. SO, I am getting a choke collar for control while walking her, and the stake is to attach to a chain while she is in the backyard. She won't like it much, but I really have no alternative right now.
