It's possible for them to have intercourse, but it's not possible for the animals to breed in almost all cases.

One exception would be Horse + Donkey = Mule

Though....mules are not capable of reproduction.

Dogs and Wolves/Coyote's can interbreed and their offspring are fertile.

Tigers and lions can breed, but is probably extremely rare, if it happens at all, in nature. Has to be encouraged by pairing them together in captivity I imagine. But they are very closely related, and I imagine very few other species can successfully breed with other species.

edit: OdiN provided some good examples I didn't even think about above. It seems that only species very close genetically can breed together. Not sure how often they can be produce fertile offspring, with canines being a very notable exception.

On that note, I have an aunt and uncle that previously owned a wolf/husky mix, but it was close to 95% wolf. Very untrustworthy creature if you ask me, thing terrified me. Then again, when they owned it, I was what... I think around 10, and the thing on its 4 legs was nearly as tall as me. I might be less timid around it if they still owned it to this day, as I know not to show fear around canines, but there is a limit to how much you can trust a basically pure wolf in captivity. They had to put it down when they moved to Wisconsin, as while in Ohio it was legal to own a wolf, it wasn't legal in Wisconsin... but I think to this day, I think... seriously? cannot imagine someone basically owning a wolf, awesome creatures... but insanely powerful and likely impossible to tone its instincts down... it snapped at us a few times, but never bit anyone.

Yeah, I guess dogs would be one of the biggest exceptions. Can all dogs mate with all other dogs theoretically?

Edit: I didn't have to think about my question long to answer it myself, lol...

What exactly determines whether a species of dog could have offspring with another?

Obviously we don't see many, say.. golden retriever weiner dogs.... :laugh:

I wonder if say...jaguar/panther?

But yeah there are very few instances, and maybe one in which the offspring is able to reproduce.

Well we have crap like labradoodles, etc. Lots of different breeds, not sure if they all work interchangeably, but that would be interesting.

Dogs are essentially all the same species iirc. I don't think a lab, poodle, or even huskies or german shepherds are considered different species. Just bred for distinct purposes, and they all came to creature different lines of different looking animals, aka breeds. It might, in one sense, be comparable to the different 'races' humanity has, with things like hair, eye, and skin color, and even height, being different among the different 'races'. We are all the same race, mankind, but have different appearances based on, well... selective breeding.

Sweet, another opportunity for that soon to be Ph.D in biochemistry to get put to use on here. Dogs are domesticated wolves and it really is splitting hairs when it comes to labeling the breeding of the two "interspecies". They are, for all intents and purposes, genetically identical (not in the clone sense, but in a similarity sense), FAR more so than say humans and some upper primates. What it really boils down to is:

1) Can they physically mate (which can be bypassed by artificial insemination, in vitro fertilization...ect ect). While genetically, a toy poodle and a great dane could produce offspring, physically it just isn't going to happen (and if it I'd feel sorry for that poor poodle)

2) Genetics. We can go by number and size of chromosomes, locations of essential genes, lethal autosomals, and general lack of fitness for survival (mules being sterile...ect)

Now, should you be hell-bent on having a pet piglizard, it is more possible than you may think. Modern labs create chimeric animals far more often than most people are aware of. Some of you may remember the link on DailyTech about the "clones" extinct (tasmanian tiger I think). The disappointing part about this is that at this point in time, we are simply swapping in a copy of a HIGHLY similar gene (think something highly conserved throughout animals, like hemoglobin or insulin or something along those lines). While technically the resulting animal is genetically constituted from 2 animals, the phenotype (outward, physical appearance) is indiscernible from any "normal" specimen. Some day, however, we may be able to splice more interesting genes in. Think of the cuteness factor of a puppy-kitten or the badassery super villain-esque Bear-horse :)

Well, Louisiana's residents are mostly the children of Neanderthals and donkeys, so I'd say interspecies breeding can definitely happen, as long as you go to church every Sunday and pray for it.

Very interesting.
Any links to documented cases of these chimeras?

Why a bear-horse when you can have a bear-elephant?

I'd hate to follow that thing around with a shovel.

What about an eagle-snake.

Creepy thread. IIRC, it depends on the similarity of chromosome count. And even then, the offspring is likely to be sterile.

All dogs are the same species. Canids (dogs, wolves, foxes, coyotes, etc) in general are all closely related genetically and IIRC can interbreed. While science believes that dogs evolved from the domestication of wolves, an interesting study I recall is a Soviet scientist who experimented specifically with making foxes more tame and within just a few generations had a dog. Very flexible DNA throughout that whole family.

Kinda what I was thinking.

Unlikely.
