My neighbor on one side has a very old, very fat, and very sweet chihuahua.
She can hardly see, but still manages to toddle towards me if I greet her on one of her outdoor excursions.
People across the street used to have a Silky but I've not seen him in ages, so he has probably crossed the bridge. He would be quite old if not.
Directly behind us is a dachsund who appears to hate everyone and is never leashed when outside, but usually doesn't leave her yard -- except to charge at me! If the neighbor wasn't so nice, I'd be livid.
Two doors from them are the neighbors from hell when it comes to pets. They have ANOTHER dog that barks virtually NON STOP after the first dog "ran away." The first dog was mostly kept outside and chained up, half the time with no water or with filthy water. He was a really nice dog. Very sweet. But he kept breaking his chain. We returned him on multiple occasions. (to keep him off a four-lane roadway). I got him water all the time.
Last year, they went out of town for several days and left the care of the dog to a family member who lived nearby. Dog broke the chain again and a Good Samaritan tried to return him. They weren't home. When she saw where he was kept she said there was "no way" she was giving him back. (Some might disagree, but there was no way I was going to discourage her or tattle on her. That poor dog was destined to be roadkill one day anyway so maybe this way he got a better life.)
