I love dogs, hope to get a golden retriever when I get my own place.
Dogs are wonderful - they were the first species to be domesticated and now they are selectively bred for various characteristics. 
makes sense, using them for hunting and protection was soemthing people needed, now they are our cute best friends.
yes because the dog and the extinct gray wolf are sister taxa whereas modern wolves are not closely related to the first wolves that were domesticated.
