Do dogs cannibalize other breeds?

I still don't understand how the fuck a wolf is selectively bred into a chiahuahua over the course of thousands of years.

Thousands of years is nothing.

" Small breeds tend to mature faster than large breeds. On average, however, males become fertile after six months of age and reach full sexual maturity by 12 to 15 months."

"An average litter consists of about five to six puppies"

Then i think you just keep cross breeding till you get what you want

that's 7 thousands of years, tho

My brother's dog killed and ate several of the neighborhood dogs. It was a mix breed of Bully Kutta, Kangal, and English Mastiff. It pretty much killed and ate anything and everything. A neighbor has a pack of wolfdogs. I've no clue what they are crossed with, but they are the largest dogs I've ever seen and all snow white. They also kill and eat anything and everything in the area if they get loose. If they get loose she has to call some special dog swat team hotline to get them back and helicopters are dispatched to find them. They've only escaped once.

They didn't take 1,000s of years to make them though. Making a new bread is a fairly simple task and shouldn't take more than a couple 100 years.

Were the dogs of smaller breed or did the dog eat any type of dog?

For natural selection.

Artificial selection is natural selection on the most potent steroids imaginable. It's like the difference between prime Arnold Schwarzenegger and current Stephen Hawking. Which is actually an OK analogy because huge steroid use can cause some bad side effects as well.

I've got a batter question. What if you inseminated a chihuahua female with the sperm from a great Dane?

Would it even work?

In theory I don't see why not, but I wonder if the brood would be too large for the chihuahua and threaten its life. I guess we can only find out by experimenting.

The key lies in short lifespan and maturity rates. It's the same reason why we were able to customize the genome of plants so much before modern genetic engineering came to be.

It's also the same reason why insects are so diverse. Shorter lives, quicker maturity, faster breeding, higher mortality, rapid mutation.

Think about how many generations of dog/plant/insect you could generate in a thousand years. Then think about the difference in results you could get between first generation and last generation within that thousand year span.

This is also why humans in comparison seem to change so slowly. We live much longer and while we can have kids at a young age we have actively applied pressure on ourselves to live longer every generation.

It's come up occasionally, but if the mother is the chihuahua a c-section is necessary.
