Last summer we got our kitchen remodeled, and the company that installed the counters, work all over northwest Ohio. When they first got here, a couple of dogs met them at the door, and as usual, I had to explain the breed.
One of the guys said "Hey, the house we were at yesterday had one of those!"
I asked him where and when he told me the town, about 2 hour from here, I looked up the address of a puppy from me that lived in that town. I asked if he was at (that address), he said yes, and I told him "That dog came from here!"
I have not bred a litter in 11 years and after the puppy is a year old I only have contact with the people if they contact me.
(Except, I remember emailing folks to let them know the DNA fanconi status of their dog's parents and what that meant for their dog. )
