Those were Russian foxes, not dogs. I found that story fascinating on what happens to wild foxes as they are domesticated. I wondered if other domesticated animals (like cows, chickens, etc) went through such physical changes as they were domesticated for use by humankind.

Have not kept up to date on it, but last I looked the Asian wolf was suspected to be the ancestor of domestic dogs. Domestication happened at least 16,000 years ago BCE. Check out the dingo line of dogs to get an idea what early dogs looked like. Also, my favorite the New Guinea Singing dog, also called the Highland dog.

There is such a thing as recessive genes. A recessive gene can make itself apparent anytime in the evolutionary process. Mating two "purebred" dogs can, at random, produce offspring totally different.
Wolves possess recessive genes, so if some wolves produced little dogs, or different color dogs, or long-eared dogs or any other trait, those "unusual" offspring can be bred to each other over (many) years make the once-recessive traits now dominant. Then eventually, the American Kennel Club recognizes something as a "new breed" for pedigree purposes.
Simple.

Dang! I didn't scroll down enough and was just about to post this one. I think this explains it all...

They are from wolves. DNA comparisons show that very clearly. The majority of the breeds around today were developed over the past 200 years from older domesticated breeds of dogs, but of course their earliest domestication started many thousands of years ago. An interesting recent documentary about the evolution of dogs is here: https://www.pbs.org/video/dog-tales-vskr2y/
I thought I knew a lot about this subject, but this documentary taught me a lot!

Some of them might have morphed into politicians. The Russian foxes, that is.

Commercials will say almost anything to sell a product. Personally I feel commercials are an insult to the intelligence of humanity. Just my $0.02 worth of personal opinion.

Breeding is the reason for wide range of dog breeds. For instance if you take the runt of the litter odds are the offspring will be smaller, keep repeating and you get smaller dogs. Fundamental to animal husbandry.

You know the problem with instant gratification, it just takes too long, or so I have been told.
