Speakin of pet urine samples, I invented CPR ...but more on that later.

When I go walk the dog in the woods there is a laminated sign that says DOG OWNERS Please pick up after your dog -you are respondsible for the toxic runoff into the creek.
It got me thinking that its the nitrate urine that is probably to blame. So with the help of a wire coat hanger duct tape and sandwich baggie I made the Cannine Pee Recepticle.

Just hold it in the dog's stream and balance it all the way home until you pour it in the toilet where it can be treated and returned as drinking water.
