I have had two dogs for the past twelve years. They have been best buds. Cinnamon and Chipper were both Puggles, half Pug and half Beagle, the weren't from the same litter but they sure thought so. They were both the same age. So really they were like sisters.
If you spend any time on social media like Facebook and Twitter you see it. You see that there can be some really unlikeable people around. Spend any time talking to any animal shelter and they can tell you the horror stories.
