Summarize this article in one sentence.
If you were able to get the urine sample, congratulations! To prevent the urine from spilling out or getting contaminated, cover the container as soon as you can. If you're using a container that has a matching lid, use that lid to cover the container. If you used a pie plate, pour the urine into a container with a sealable lid if possible. Otherwise, cover it tightly with two layers of plastic wrap. Wash your hands before and after covering the container. A fresh urine sample will provide the most accurate urinalysis results. Ideally, the urine should be examined either immediately or within a few hours of collection. After collecting the urine sample, take it to your vet's office as soon as you can. If you can't drop off the urine sample right away, you'll need to store it at your home until your appointment. Because the urine will need to stay cool, place the urine sample in your fridge or on ice in a small cooler. If you choose to store the urine sample in the fridge, wrap the container in a plastic bag first. If you're not comfortable having the urine sample close to your food, a cooler would probably the better storage choice. A urine sample more than 12 hours old is no longer fresh and may not give accurate results. If more than 12 hours pass between collecting your female dog's urine sample and the appointment with your vet, let the vet know how old the sample is, so they can decide if it will affect the results and if a new sample is necessary.

Summary:
Cover the container. Take the sample to your vet's office. Store the urine sample in a cool place.
