Chelsea's mom says: Chelsea is my nine-year-old Sheltie who think sheâ€™s still a puppy. She loves to play Frisbee or "stick" and lay on her front step to guard the neighborhood. She likes to go in the boat and go rafting. At Halloween she likes to greet all the trick-or-treaters. Christmas and birthdays she will help open all the presents. To keep cool, Chelsea loves to lie on any snow pile she can find.
