Thx for posting this. I always assumed that canines could interbreed.

well, except for the canines, who seem to be able to breed with everyone in their family and produce fertile offspring. I'd love to get a pygmy geep if the drought ends and my grass starts to grow in the front yard again.

Coydogs, wolfdogs, coywolves and I am sure many others in other parts of the world.

My wolfdog is snuggles up on my bed. He has a grandparent that was a wolf. I am against the breeding of wolfdogs, mine was a rescue and was lucky to have only good wolf traits like the needs to be very close to his pack at all times. This negates the roaming tendencies of the husky in him. Often times this is not the case. It's a roll of the dice every time one is bred.

even though canines have been selectively bred to have some parts expressed over others. With sheep and goats, the divergence occurred a million or so years ago and parts of the genome in each have been degraded beyond repair. It's why hominoids and chimps, who interbred a million and a half years ago, can't do so now, even to produce sterile hybrids.
