My Boo was a rescue dog. The humane society called and said there is a dog and 7 puppies that need a foster home. Can you go and pick them up. Of course, I said, right away. She was a mix of lab and pit bull. The puppies were adopted out and Boo had heart worms. So, we kept her a little longer than usual and ended up adopting her. She was the sweetest, gentlest except for other dogs. There were 3 instances of dog attacks on her part. Because of her aggression, I had to put her down. Could not find any one to adopt her. I loved her so much. But she had this zone that she would go in and you couldn't reach her. She sailed over my fence one early morning and attacked another dog. Thank God she did not kill it. We had been thru so much drama with her and these attacks that I finally for the sake of her, the neighbors and us let her go. We gave her two good years. She was about 4 or 5 yrs old when we got her and we loved her and cherished her and helped her in every way possible, but it just wasn't enough. My Boo went to that place I hope all doggies go and she will be free to enjoy all the doggies of the world. I loved her so much.
