I have a dog because she keeps me company,I don't like feeling alone and she provides me with that companionship. Peanut has to be one of the most loving dogs I have ever owned,I'm not sure if it is because of her breed or not but she is so spoiled and adorable,she is a chihuahua and corgi mixed. Pets impact our lives more then we know it I think and she sure has more then anything,at night she sleeps in the bed with me and I absolutely cannot sleep without her,guess kind of became dependent on that. We also have other dogs in the house,male dogs that is who guard and protect us at night,they have a little pit-bull mix inside of them and so people always are scared of them which is great for the protection so they don't mess with our house.
