I really like dogs and have two myself. I know they come in many shape, sizes and colors and are great companions. Do you like dogs?
I love dogs! I have a Lab myself, what kind of dog do you have?
I have a Chihuahua and a Shi-tzu. After getting mine, I can see why they are termed, "man's best friend", but woman's best friend applies too!
I had a Shi-tzu as a kid, he was naughy but fun.  Do tou know how long have dogs been living around humans?
I don't know that, but I do know they were the first species to be bred domestically. Of course, they have been continued to be bred throughout the years for various reasons, including behavior, physical attributes and sensory capabilities.
