Peeing to a dog, especially a male dog, is so much more than just emptying its bladder.
It’s all about sniffing and interpreting the sent of other dogs and staking out one’s territory and a whole lot things we humans simply have no idea about, depriving a dog of this important part of his natural behaviour is not something I would do to my dog.
