I currently have 2 cocker spaniels.
Yes I like dogs because they are  members of the genus "Canis" (canines)
They are very loyal animals.
wolves are  the direct ancestor of the dog is extinct because  dog and the extant gray wolf are sister taxa
That's interesting. How long have dogs been pets?
The dog was the first species to be domesticated and has been selectively bred over millennia
That makes a lot of sense. 
It would interest you to know that  show that dogs have mutations to equivalent genetic regions in humans
