What a relief to have this Fire Hydrant in your dog park! Dogs may see in black and white, but that doesn’t make this bright red fire hydrant any less appealing to them. The Fire Hydrant is sure to be the most popular place in the dog park. It creates an obvious area for dogs to mark for the next visitors to know that they were there. Providing dogs with another area to mark will discourage them from marking other items that you want to keep urine free.
