Pee in their water?

I don't know if it's any account or what but when I'm feeding my dogs if the notion strikes me and I got to piss I'll pee in their water, on them, or right at the entrance of their dog house and most of the time my dogs want come to anyone else but me, It's my theory that they learn to recognize your scents as well as your pheromones in your scent, it could just be all coincidence or there could be something to it idk, I also read in an article once that in a pack the dominant male will piss on their others dogs in one of the ways he shows his dominance , as far as the dog laying at your feet and getting timid, watch other dogs behavior when there is a dominant one around they do the same, I have a gyp that if she's around people she has an uncontrollable shake, but will leave and go do her job once I get her away from crowd, she's very timid acting and other than the hard hand a few times while she was a younger dog she hasn't been abused bc I raised her from a pup and neither parents were like that either.
