That's okay! Just avoid shared food and water bowls for a few hours.
To ensure that a good swab sample is obtained, it is best that your dog does not share water or food bowls with another dog for at least two hours prior to swabbing.
Do NOT use the same swab for multiple dogs as it will prevent results from any of them.
