Feist - Must be what our dog was. She was about that size, but her coloring was more like a German Shepard. She showed up one day and adopted us. About that time, I was doing road races and marathons. She would always go along on my early morning training runs. Even the 18-22 long Saturdays. It was her favorite thing. One Sunday morning after a snow left about 6” of fluffy white stuff, while helping #3 son deliver papers, we spotted a squirrel that had decided he wanted to be in the other tree. It was too far to jump, so he was hopping in the deep snow. Bad mistake. Dog was a bunch faster in that terrain. It was a sad day when my wife took her to the vet, but she was completely used up.
In her younger days, she took to attacking the clothes on the clothes line. I rigged the electric fencer to the clothes line and watched to see what would happen. She approached the sheet, didn’t touch it, and never bothered anything on the line again.
They are special for sure! It sounds like she was special. I have had a lot of good dogs in my life but none like Abby. Thanks for taking in your girl. Strays often make the best dogs.
