Correct me if I'm wrong but Dogs are the best thing to ever happen in this world. 
Absolutely without a doubt! I love dogs. They are a member of the genus "canis" (canines), which forms part of the wolf like canines and they're the most widely abundant terrestrial carnivore!
I wonder how long they have been man's best friend?
That's a very good question, the dog was the first species to be domesticated and they have been selectively bred over a millenia for various behaviours, sensory capbilities and physical attributes. Truly a mans best friend! 
Wow, How interesting. I have one a Pitbull and when i'm looking to adopt another soon.
I would love to adopt a dog soon but not sure which to get, i like pugs but they have poor health so maybe not. They are actually referred to as mans best friend because of the influence they have had on human society
I found my eating out the dumpster and loved her from day one. My plan for my next down is to adopt who ever had been at the shelter the longest.'
Wow, i have so much respect for you! Thats what i should do, its a great idea. The good thing about them is, there's a dog for everyone because they vary widely in shape, size, colors and personality.
Yes, My dog is very large but my last that died of old age with tiny.
Sorry to hear that, i would love that bonding experience with a dog though. It's amazing how dogs can perform a variety of roles for us like hunting, herding, pulling loads, protection, assisting military etc.
