Class Fox?

As a kid visiting a zoo did you ever wonder what it would be like to pet the tigers?  Well as you know wild animals are dangerous and they aren’t meant to be tamed, patted or touched… or are they?  According to new studies domestication may not be a learned trait or a trait only found in our dogs, cats, birds and livestock, but a gene that can be bred into wild animals through selective breeding.

In Russia dating back to Stalin’s rule scientists began to wonder if they could breed domestication into a population of animals.   They decided to run their experiment, despite the risk of death because of the government’s aversion to studies on genetics, and started out by heading to fur farms and selecting the calmest foxes who showed the least amount of aggression toward humans.  They began to breed these friendlier foxes and with each generation they began to get friendlier and friendlier foxes to breed.  Today the foxes react to people much like a dog would; they start jumping at the front of their crates and wining for attention and will leap into your arms at the first chance they get.  In fact these foxes even resist going back into their cages because they hate to leave human attention that they love so much.

So how do we know that it’s genetic rather than behavior changes in these foxes?  The scientists thought of this and they kept a control population, for this population they continually bred the most aggressive foxes and got highly aggressive animals that hated human presence.  To test out their theory that this was in fact genetic these scientists took one of the pups bred to be aggressive and gave it to one of the friendly mothers, despite being raised by a mother that loved people this fox remained aggressive to people, as it was bred to do.

Another reason that they are confident that this is genetic is that the foxes physical appearance began to change, they started to look more puppy like for longer, their ears stayed floppy longer, they developed white specs on their coats and their tails curled, all of these traits are typically seen as traits that humans like and that would make the foxes more dog like and more appealing to people.

It may seem hard to believe that a wild animal can be tamed simply through breeding but the reporter of the original article fell so in love with these foxes she now has two sharing her home with her, and her golden retriever.  The scientists and now working to get permits that would allow them to sell some of the friendly foxes as pets (to help fund their research), which leads to the question if we are given the chance to buy them would you ever own a Pet Fox?

    As an animal lover, i know i would love to have a pet fox on my farm(that i dream of one day having)! Unfourtinalty, this article reminded me of an article had read on my dream dog, the English Bulldog. Aside from my mom not letting me get one, I don’t know if I would ever let myself get one because i know i can’t deal with their tragically short lived lives. Although these foxes seem to only have great effects from their breading, bulldogs are said to be the “most extreme example of genetic manipulation in the dog-breeding world that results in congenital and hereditary problems”. That irresistible pushed in face did not just happen, it was made through breeding, but it is also the source of their breathing problems. I love them so much that i am now to “question(ing) whether it is ethically defensible to continue breeding them at all.”

    YES!!! I had been reading about this over the summer in an old national geographic from the ’80s while I was at work (but someone threw it out before I had time to finish it 🙁 ) and it was really interesting. The article was from when they first started trying to domesticate foxes in Russia. (I couldn’t find the original article, but this is a follow up on it:

    But this wasn’t the first time I’d heard about domesticating foxes! Strangely enough, my cleaning lady told me that when she lived in Poland as a girl, they had a fox farm. One the farm she actually kept a few of the foxes as pets and her German Shepard even raised a litter of foxes after the mother died!
