Ask a Dog Vet and Get Answers to Your Dog Health Questions
I am sorry to hear that your dog passed away. My sincere condolences.
My name is Rebecca. I am a veterinarian and will do my best to help.
Hair does not contain DNA. A hair follicle might contain DNA, but hair that is shed does not usually have a live follicle attached; the hair is shed when the follicle dies or goes dormat. Also, the companies in the business of identifying breeds by DNA normally use a sample from the inside of the cheek and are not set up to extract the DNA from another source.
Let me know if I can answer anything else. I am sorry your dear dog is gone. Rebecca.
I hope you were able to see my answer. Was this helpful? Can I ca swer anything else?
