I've been reading much on the subject lately. I have required a puppy that is a wolf/dog hybrid, he heeds special care and containment considerations. I don't know the exact wording but I'm sure you'll correct me becaue i know I'll be wrong. Canis lupis is the wolf? Canis canis is the dog? I have read recently that the scientific community have done away with different classifications between these animals because they are all the same species. There was no speciating. Wolves being designer bred by man for certain specific functions did not speciate the wolf into a new species.
Are horses and asses the same species? They are close enough to produce viable offspring, yet those offspring themselves cannot procreate. We call them mules.
