Our home is in the country, but it's not far from a busy highway and despite our best efforts, our dogs would escape from the yard and die on the highway or sometimes just disappear. They would go under, through, or over the fence. Or failing that, they would sneak through when we had the gate open.
We've had quite a few dogs over the years, sometimes as many as three at a time. The first few dogs were 'store bought' and the rest were drop-offs by persons unknown. I have no kind thoughts for anyone who would dump a dog.
The young dog on our porch was friendly, female, and about a year old according to the vet. The dog was a mostly-white cattle-dog mix with thick, slightly curly hair. It had one frost-bit ear and a serious flinch when someone tried to pet it. It was rough and underfed, but not as underfed as some I've seen. For the reasons I discussed earlier, I didn't want it; Kathy did. Finally, I relented, and said, "If we're keeping her, we'll name her Zero because with our record, that's her chances of living another year."
That was 16 years ago, and Zero is 17 years old and counting. She was the first dog of ours that never left the yard even when the gate was left open overnight. Now she's deaf, about half blind, and the arthritis in her hindquarters give her a stiff and a little sideways walk. She is prone to sudden collapses. She has no reverse. Most of her time is spent near her doghouse on our north porch. She spent the summer in front of a squirrel-cage fan we bought for her. At the time, we discussed moving her indoors, but spending time indoors seemed to traumatize her. In the end, we decided it would be best to not change her environment at her age.
17 dog-years old and counting. That qualifies her as an old lady.
