Here goes.
I took Lucky in for two weeks and then told the people they had to take him back after vacation. I wasn't allowed to have dogs. I had super cheap rent and had lived there for years. They couldn't keep him and by that time I had fallen in love so long story short, I got kicked out of my duplex because I had a dog.
Lucky was very sweet but not very smart. He got out of the yard a couple of times and I found him by asking people have you seen this dog. "Oh yeah, I saw him, he looked so lost."
I taught Lucky some basics like heel and sit and down. Eventually, I decided to teach him to shake hands. Granted, I wasn't super consistent with training but he did well on sit, stay, down, come and heel. One day I told him "Shake hands" He was sitting in front of me and you could see the wheels grinding inside his little pea brain. "If only I could figure out what it is she wants, I could have that treat." He thought and he thought hard. He just couldn't come up with the answer. I decided that he was full up on the amount of knowledge he could accumulate and settled for a nicely trained sweet little dog who didn't know any tricks
Not that he was that good at heel. He seemed to have some hound dog in him and would run after squirrels and such. You couldn't let him off leash. One time, in Texas, we were driving a back road in my Camaro, doing 35 mph. Lucky was in the back seat and I had the window part way rolled up. Suddenly, Lucky was leaping out of the vehicle and falling onto the pavement. I was sure I had killed my dog but he was fine. I think he must have seen a rabbit.
When he was a puppy, he would steal things from the house. I would go into the backyard and there would be a pile of treasures, completely unchewed. So cute.
Lucky had a series of small strokes as he was getting fairly old. He recovered after each one of them but he was so dumb to begin with, you couldn't really see the effects

One day, Hubby was peeling apples and the peels were dropping from high up directly into the trash can. Lucky watched in amazement like it was a magic show. "How does he do that? Where do those peeling go? Doggy Daddy is amazing."
I had that dog for fifteen years and he was so sweet and cute and fun and dumb.
