Dog DNA test; decoding your mysterious mutt

dog dna test

Do you share your life with a magnificent mutt? Have you ever wondered what lies beneath that loveable exterior? A dog DNA test may hold the answers for you.

Despite being around since 2007 dog DNA tests have only recently become popular for dog owners.

But can a dog DNA test actually provide any useful information? Or is it just a way of satisfying our curiosity about our dog’s history?

Actually, knowing your dog’s ancestry can provide useful insights that may help you better understand your dog’s character traits, and appearance.

But perhaps, more importantly, any genetic predisposition for particular illness or conditions.

How does at-home Dog DNA Testing Work?

Several companies offer at-home dog DNA test kits. Simply order the test kit online, and you will receive everything you need to take the DNA sample at home.

Once you receive your kit, read the instructions carefully. The DNA sample is usually gathered by taking a cheek swab from your dog using a small brush that is provided.

However, most kits suggest a wait time after your dog’s last meal. And also require you to air dry the swab before placing it in its return container.

Follow the steps carefully before sending the swab back in the prepaid envelope. Then all you need to do is to wait for the results that are sent back to you usually via e-mail or via password access online.

How do they know what my dog’s ancestry is?

OK, so you’ve taken a sample from your dog and sent it back as instructed. But how does the DNA of your dog help identify what breeds are in its ancestry?

Each of the companies that offer DNA testing has an existing DNA database of the most common pure breed dog breeds recognised by the Kennel Club in the USA and in the UK.

During the process of analysis, the DNA markers in your dog’s sample are compared to the thousands of DNA markers contained in the reference database.

So, if your dog has DNA markers in common with a dog breed in the existing database, its ancestry can be identified.

But what happens if your dog has parentage that is not recognised by the Kennel Club in the USA or the UK? Or what if your dog is the result of many generations of mutts?

How accurate are dog DNA tests?

Most of the dog DNA tests are accurate in identifying the breeds of a given dog if they have a pure breed within three generations, parent, grandparent and great-grandparent.

However, if your dog’s genes have been diluted over many generations of mixed breeding, it can prove more difficult.

Sometimes called village dogs, these are the type of dog that people used to refer to as mongrels¬†or Heinz 57’s.

In these cases, the gene pool is so diverse that any trace of pure breed lineage may not be able to be identified in the DNA results.

While current tests are not perfect. The accuracy of the results is increasing as more breeds are added to the company’s databases.

How to choose a DNA test

Every business that offers a dog DNA test uses a different database, and some of those databases are more extensive than others. This means that the tests vary in the number of dog breeds that can be identified.

Also, while all the tests provide breed information. Only some will give you potential health risks associated with the ancestral breeds.

Not only does the information vary from test to test but also turn-around times differ and of course so do the cost.

So what are the top dog DNA tests on the market? We’ve rounded up the three most popular, Wisdom Panel Insights Dog DNA Test, Embark Dog DNA Test and DNA My Dog. All of the tests mentioned use cheek swab samples that you take at home.
