One Step Dog, Cat, Pet Urine Test Strips | pH,
This will help it stand up when you are using the test strips, though I had to support it anyway using a heavier sacrificial cup. Then, with your dog on a leash, take him to his favorite potty spot that is not buried in bushes (think fence post), let him lift his leg, and sneakily slip your cup on a stick into his urine stream and gather your sample.
