What If I Have More Than One Dog In My Home?

The sharing of water bowls or toys does not tend to transfer a significant amount of DNA from one dog to another, so is not cause for concern regarding sample quality and cross-contamination. However, if your dogs are prone to play-biting or roughhousing, it may be best to separate them for at least an hour before swabbing, to ensure no skin cells from the other dog are present in the tested dog's mouth; this may cause the sample to fail.
