Lloyd, that the way I'm with labs and shorthairs like GSP and Weims. Must wash hands immediately. And like you, I have confused a few dogs by my lack of physicality with them.
I even used to have a cat or I should say the cat had me. The first five years or so was fine. And as cats will, he decided I was his. Little interest in my wife. But then the allergies came and the last decade of his life I had to increasingly stay away from him and anything he touched. I even could tell when the cat had been crawling around on one of the dogs! He was somewhat perturbed by my change in behavior.
