i love dogs
Me too! I have two. They were actually the first species to be domesticated for households, it's no wonder they are man's best friend!
Yeah! what do you mean by domesticated?
I mean as in they were bread and trained to be in the house, from when they were wolves in the wild at some point. The direct ancestor of dogs were wolves that are now extinct, crazy right!
Crazy? not really! its just some facts you are simply exposing. So why are they called human friends?
I just mean its crazy how they evolved over time, not my comments haha. Their influence on society has given them the name "Man's Best Friend" 
So are there specific number of dog breeds that exist today?
I'm not sure, I'm sure there are 100's. They come in all shape, sizes and colors.
So which among the breeds of dogs is your favorite?
I love yorkies! I had one growing up, you?
