If you have a dog who urinates on concrete, there are a few things you can do to clean it up. The first step is to take the dog’s food and water off of the patio and put them in a bowl. Then, take the pet’s toys and put them in another bowl. Finally, take the concrete off of the patio and place it in a trash can or bin. Once all of the pet’s food and water has been cleaned up, put it back on the patio. If there is still any urine left on the concrete, you can use a vacuum cleaner to clean it up.
