It is loyalty to the extreme where it appears your 4 legged friend wants to be by your side ever waking and sleeping hour. Although you may believe it’s for the snacks and fun times they actually stay with you through the rain as well as a storms of your life. Maybe there so loyal because they don’t really understand us as a whole and only see our cup as 1/2 full all the time. As extreme as it is it’s good to know someone is always there for you even if she/he has a tail between their legs.
