Out of all the pets you can get dogs are my absolute favorite.  Its no wonder they were the first species to bet domesticated.
They're such loyal and kind animals, as well as how many uses they have!
They really do have many uses.  They provide their owners with physical and emotional benefits.
They were also used for things like herding and retrieving right?
Yes that is correct.  All herding behavior is actually just modified predatory behavior. 
Oh that's a really interesting to think that we basically recoded their behavior to make them do something totally different.
It really is.  One of the best herding dogs is actually a collie and they look very different from their wolf ancestors. 
Collies are great dogs! So smart and energetic!
