This soft silicone catch tray with integral urine specimen jar attaches to your male or femal dog in seconds and does not hurt your dog in any way. The jar unthreads easily after dog pees and a new included cap seals the jar. You then give that jar to your animal hospital for them to do urine lab testing. The straps are soft elastic bandage material with small strips of velcro attached for easy attach and stretch to accomodate varying dog sizes. The final product will be much more refined as these are prototypes.
