What is DNA test

Hi can anyone please tell me what DNA heath testing is
what is the test and what dose DNA stand for... why do we need to have
the DNA test... are there any other test we should be looking for when getting a puppy

An animal's DNA is it's genetic make up & stands for Deoxyribonucleic acid.

DNA research is basically into the dog's full or part Genome & is usually linked to a suspected or known genetic condition.

Depending on the breed there made be no, one, a few or several DNA tests.

The main DNA testing company is Optigen in the USA & The AHT in the UK & there are some others

The DNA tests that should be done on breeding animals before being bred from depends on the breed & the KC do have a sort of list of tests that should be done, but IMHO if there is a test available & the dog isn't from generally normal parents, then all available tests should be done
