A lot of text in this one, but I could not resist narrating it. It's a story about how humanity transformed a large predator into a doll in a few thousand years. Most of the changes actually happened just during the 20th century.

Many dog breeds have serious health problems that are caused not only by inbreeding but also because with such a distorted anatomy, it's simply impossible to produce a healthy animal. I think we have no right to cause such pain just for our own aesthetic pleasure, however lovely pets they might make.

I produced a series of these dog breed skulls for an article I wrote about the genetics of dog and fox domestication.

Update: the article is now translated and posted online. It can be found here: [link]

This deviation brings this to mind :…

If you check out some of the primitive rat-weasel creatures that were ancestral to dogs, like Hesperocyon from 40-35 million years ago, you'll note that dogs started out as rat-weasels, evolved into badass wolves, and then humans showed up and turned them back into rat-weasels.

Actually, Hesperocyon would fit pretty well in between the second and third skulls you listed.

Even though said overly exaggerated genetic traits do cause serious health problems they are still a fascinating case of how humans have managed to drastically alter the appearance of an animal in a few thousand years compared too millions of years of natural evolution. Top notch effort as usual Euwentala!

I absolutely do not support such inbreeding or anatomy altered to the point where health is not possible, but I would like to bring up what I think is an interesting point (particularly with regards to your article) - humans themselves are the result of neotenous mutations. All human beings have what would be considered major neotenous characteristics in our closest relatives, the great apes. 

I think it's very interesting that we tend to, even subconsciously, alter animals to be more like us.

It's kind of insane that people promote the breeding of traits that are outright harmful. Wanting a certain coat color, fine, certain ear type, whatever. But a smooshed-in face that makes it harder for the animal to breed? Stout figures that make it harder for them to run around and unable to mate and give birth without human assistance? Some of these animals practically look deformed.

The fox domestication project is an interesting topic. I can't help but wonder what other animals we could domesticate so quickly, if we put the work into it. And if we gave such projects thousands of years like we did with dogs, maybe they could even produce the same variety.

Yeah, but apparently most people simply cannot see the animals they love and breed are suffering, however obvious it is to the outsider.

I think some animals (say, those that are social and docile to begin with) would be easier to domesticate than others, but I'm pretty sure that most mammals, at least, could be domesticated very quickly if we put some effort into it. And the foxes are already showing signs of dog-like diversity: they have an increasing number of piebald colors, floppy ears, curly tails and so on.

I guess they grow to see that kind of thing as normal. I often see snorting being described as a "characteristic" of certain breeds like the pug rather than being called a health problem.

Agreed on the domestication thing. I'm surprised it hasn't been attempted more, since there are so many people who want exotic pets without having to put in the extra work it would be compared with a domestic animal.

I knew, they have problems with breathing and other painful difficulties, but looking at the skulls... Oh, my! So grotescuely deformed!
