Thank you for the information, I also need to check the breed of my dog because my friend who gave me this dog is a mixture of pitbull and Labrador but all I can see is she is a pure Labrador. By the way, I saw this dog DNA Test Kit, it is the same with your explanation that I need to swab my dog's cheek then I have to send it to them and will receive the results in two weeks. What do you think about this product?
