In my country, there are little parks where dogs do their business. If you walk with a dog in public places, you are expected to have means for cleanup with you. If your dog soils the road, you're expected to pick it up in a tiny plastic bags and throw it in a garbage can. Violating either rule carries a fine. There is markedly less dog poo than there used to on the roads. Which demonstrates grandparent's point. There are solutions to the problem. Nobody got rid of the dog, and dogs still pee and poo. There just are technical and legal means to keep the problem managed, even if not perfect.
