Test of swab of the cheek of the dog or a blood sample of it.
Step-by-step explanation:
Identifying a breed of a dog is done with a number of tests which are done either by taking sample of blood or by taking swab of the cheek of dog. The swab test is a part of the Heritage of Canine. Testing the gene from its blood sample is a most common way of identifying breed, but it is often regarded as inaccurate.
While opting for a test one should consider the type of test, breed number and budget. Cheek swab test is not painful, non-invasive and can be performed at home.
