Do you have a dog. I'm more of dog person, than a cat person,
Yes I do have a golden retriever! He's getting old though! What about you?
Yeah, I have a beagle mix. The dog was the first species to be domesticated  over millenia 
Haha, and they're probably still the hardest to train. They're crazy, and have so much energy. Very sweet though. 
They have a long association with humans which led them to be uniquely attuned to our behaviour
Yeah, I always thought they were adapted to hunt with people riding on horses. So they need to run a lot to burn all their energy. 
Yeah, and they come in such a wide variety of sizes, shapes, breeds,
My favorite is probably the Burmese Mountain Dog. They're like giant teddy bears!
That would be a shedding nightmare, but probably worth it. They aren't called Man's Best Friend for nothing.
Yes, I agree... I have a friend who has one. He looks like a Woolly Mammoth!
