Ken,
I don't think the deer can distinguish the difference in the smell of pee. However, I can guarantee they will be able to smell where you or the dog were standing and peeing.
I wouldn't think the pee would bother them, but the particles or smell from Norman's fur, foot pads, your clothes, boots, hair, etc. would be the smell a deer picks up on.
Try peeing in it without Norman there first, and then take him. I'm curious to see the results.
O'Yeah, drink a big ol glass of water before you leave the house. :D
