Inside an animal shelter, healthy, loving pets wait for a family. For the lucky ones, going home with a new family can be the best day of their lives. "I Need Love" music and lyrics courtesy of Daylight for Deadeyes.

If we went back in time to before humans there were no animals that we would call dogs. I think that is what she meant. So... In a way, we are responsible for their existing, in my opinon anyway.

If we took a modern day dog, and went back in time and found a pre-human dog, the two of them would be able to produce successful offspring, meaning that even before humans they were still Canis familiaris.

There were no pre-human dogs as I know it. The first Canis familiaris appeared around 1500 years ago but Homo Sapiens evolved between 500,000 and 250,000 years ago. That is a big difference.

P.S. The Grey Wolf; Canis Lupus evolved about 100,000 years ago, so don't go down that route either.

You dropped a zero there, it's 15,000 not 1500 years.

Oh yeah, thanks, I didn't see that.
