How old does the dog have to be to be tested?
We can test dew claws from the removed tissue of newly whelped pups. For blood sample testing, the dog should be old enough to have 1-3 ml of blood drawn by a veterinarian. Generally this is 5-6 weeks of age or older. After a pup has been weaned, we can accept cheek swab samples. Ideally, pups should be isolated from the dam and littermates for 1 hour before swabbing.
