 If a Skye is exercised too often, too young, especially before 8 months, they can damage their bone growth, leading to a painful limp and possibly badly bowed legs.Jumping up and down from objects, climbing over objects, running, even long walks, are all things to be avoided for the first 8 to 10 months to prevent later problems and allow for correct closure of the growth plate.Degenerative disc disease is also a common problem in short-legged dogs; as many as 10% of Skyes will suffer from it.
