A. Yes. DNA is contained in both cheek and blood cells. With today’s advancements in technology, buccal (cheek) swabs are the preferred method for collecting DNA from skin cells inside the cheek. This is true for both canines and humans alike. There is no need to obtain blood to get an adequate sample of DNA.
