Collecting a urine sample from your dog isn't as easy as collecting one from a human, but it's possible. Because females commonly squat to urinate, the trick is to discreetly slip a clean, shallow container under her while she pees. You typically need only about a tablespoon of urine to perform a urinalysis, so don't worry if you can't get it all.
When it's time to walk your dog, follow her closely while you wait for her to urinate. When she finally squats into position, slip a shallow dish underneath the stream or urine -- don't do it too suddenly, though, or you may spook your dog. If she is shy, it may take several tries before she finally empties her bladder. Seal and store the urine, or deliver it to your vet according to his instructions. Tell the vet if you are unable to collect a urine sample. He may have to collect it in the office using a syringe inserted into the bladder through the abdomen, or through a catheter.
