Maybe this isn't what you are looking for, but writing it down for comments.
I've had the same dog all of my life. Let me explain.
I had a puppy when I was a toddler and was really attached to it. I don't know what kind it was, mostly mutt. It was a funny little thing and loved water. You could turn on the water sprinklers and he would head right for them.
He liked to sleep on his back. Very seldom would he sleep any other way and not for long. He loved strawberries. Couldn't stand the man next door, so we had to fence the yard to keep him from biting. He would lay in wait for this man to go work and jump out at him. Seemed like a nice enough man and he had a couple of dogs, that liked him fine.
He was brown with medium length hair, but under his neck was a patch of white hair in the shape of a star. On his belly was a freckle the size of a dime. The only one he had.
He was my constant companion and when he died, I was about 10 years old. I made myself sick crying about it and my daddy bought me a little poodle. I couldn't stand it from the moment I saw it and gave it to my sister. She's crazy about it.
Then about 6 months after I lost him, a little dog followed me home from school. He looked nothing like the other one, but I liked him immediately. We advertised in the paper that we had him, but nobody showed up to claim him.
He stayed outside, so at first I didn't know he slept on his back. I did see the white on his chest and even my mother said it looked the same. When I found the freckle on his belly, I couldn't believe it, but everybody said it was just a coincidence. The first time I settled down with a book and a bowl of strawberries and salt(Yeah, I know, funky) He started begging for one. You could not keep him away from the water sprinklers and he was constantly wet and shaking it all over me. Now I was convinced it was my same little dog, reincarnated.
My mother cracked up laughing, when I told her this. The final thing was the man next door. He would dig out of the yard and hide in the same place and try to bite him. LOL sorry, but it's funny. They were both very small and couldn't have done any damage, but the guy would freak everytime and be on the phone to complain as soon as he got in his house. I had him, until I graduated from high school and he was hit by a car.
Right after I was married I was unloading groceries and this puppy wandered up. He was very young and didn't look old enough to be weaned. He was so fat, he could hardly walk. I went all over the neighborhood, but nobody knew where he came from. I finally decided somebody had dropped him off. There's no way he could have walked very far.
As he began to grow, a white patch of hair developed on his chest in the same shape as the other two had AND a freckle grew on his stomach. He's slept on his back from the first day I had him and he loves strawberries. When we went on vacation, I left him with my Mom. She said, he headed straight for the water sprinklers. We lived in an apartment, so he'd never seen any before.
While we were gone, he bit the guy next door and Mom told me he jumped out from the same place, the other 2 would hide. We ended up paying the guy's doctor bill and lucky he didn't bring a lawsuit. It wasn't a bad bite, but he's had enough of my dogs. LOL
All 3 dogs had the same type of personality. I still have this one and have my feet on his stomach as I type.
