We have special dog gift stores here. I have never seen a canine ballziere. However for those anting to limit nitrates from spoiling the Bay waters, one could by a CPR. A Canine Pee Recepticle is like a baggie connected to a handle that you hold just right when the dog takes a whiz. Seal it up and toss it in the trash where the landfill leeches the nitrates into the bay.
