Cindy,
My dog teaches me uncondional love and loyalty. Without her, I would be more depressed and give up somewhat on the will to live. I had 2 guiena pigs and both died last year. They too gave me what my dog has. When, I would come in the room they would squeak like crazy and come to the front of their cage to be petted. Pets ask for very little to make them happy. This is a lesson for all, it doesn't take much to be nice to others and in return a good friend will give you uncondional love. However, this is so rare in this world nowadays.
