Can Domestic Dogs Breed with Foxes?

Foxes are stunning creatures that can be found in most corners of the world. Many foxes live in areas that are fairly close to humans, and some may come in contact with domesticated dogs. But if this were to occur, could the fox and dog mate?

While a true fox and dog mix would undoubtedly create a beautiful hybrid, they are unable to be bred successfully. Let’s dive into all the reasons why you cannot breed a true fox with a domesticated dog!

Are Domestic Dogs & Foxes Related?

Some dogs bear a striking resemblance to foxes, leading many to wonder if the two are related. Though they are entirely different species, the dog and the fox are both part of the Canidae family. Other creatures in the Canidae family include wolves, coyotes, dingoes, and jackals.

While dogs and foxes belong to the same family, they are not of the same genus. Dogs belong to the genus Canis, while most foxes belong to the genus Vulpes.

Do Any Fox and Dog Hybrids Exist?

Until 2021, experts believed that foxes could not breed with domesticated dogs do to their DNA being incompatible. Because these animals are not in the same genus, they do not typically share enough of the same chromosomes or genetic material to be bred together successfully. However, everything changed when a dog and pampas fox hybrid was discovered in Brazil. The hybrid was confirmed with genetic testing.

Experts believe the dog and the fox were able to breed due to the unique genetic makeup of the pampas fox. Unlike other fox species, the pampas fox is more closely related to the jackal or the wolf. They are not part of the Vulpes genus like other true foxes, and they are often referred to as “false foxes” because of it.

While it appears that hybridization between the pampas fox and the domestic canine is possible, experts still stand firm on the fact that it is physically impossible for true foxes and dogs to produce offspring.

Why Can’t Dogs Breed with True Foxes?

As we stated above, it is highly unlikely to breed a domesticated dog with a fox successfully. Let’s break down the reasons why.

Their DNA Is Not Compatible

Because these animals are not in the same genus, they do not share enough of the same chromosomes or genetic material to be bred together successfully. Even if the two animals were of the same genus, other genetic factors would need to be compatible as well. Overall, there are many genetic reasons why a fox and a domestic dog cannot be interbred.

It Can Be Dangerous

Supposing their DNA was compatible, trying to breed a fox with a domestic dog can be dangerous. Foxes are wild animals that are much less predictable than their domestic dog friends. A fox can injure a pup severely during the breeding process. This is not a situation we would ever put a dog in.

Are Chihuahuas Related to Foxes?

Somewhere along the line, a rumor began to spread about Chihuahuas’ relation to fennec foxes. This is likely due to similarities in their appearance, as well as the fennec fox’s small stature. While the two may look similar, there is no science to support the relationship. Just like other types of dogs, Chihuahuas and foxes have vast differences in their DNA.

What Happens If My Dog Breeds with a Fox?

There is a small possibility you could stumble upon your dog attempting to breed with a fox. But as established, it is highly unlikely for a dog and fox to successfully breed. The most likely complication from their interaction is an injury to your pup. Subsequent wound infections could develop as a result.

Final Thoughts

A dog and true fox hybrid would likely be an adorable creature, but alas, it does not exist. There are too many differences in DNA for dogs and foxes to breed.

But if you want a fox-lookalike pup, you’re in luck. Many shelters and rescues commonly have Chihuahuas that need loving homes!
