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. 
Oh really? didnt know they werent related to current wolves, interesting.
there's the current Red Wolf and it's also very rare and one of the 5 most endangered species of wolf in the world today
thats sad, never want to see a species go extinct.
At least there are other types of wolves like the Eastern Wolfe, which is also called eastern timber, Algonquin and deer wolf, native to NE of NA Great Lakes.
