|This dog I dig..|
I do not own a dog but I do know this; When I greet a dog for the very first time and bend down to give my warm exchange, this instantly makes me smile and feel good inside as the "doggie voice" comes out of me while I am petting away. This takes place about twice a week on average with myself. Dog owners get this feeling multiple times every day.
Let's toss in the loyalty factor here. Dogs teach people about love, loyalty, and true companionship. It is a dog's duty to do this and no other creature does it better than your dog.
Dig on your dog. Your dog will dig you back.
