Dogs are very agile and athletic by nature; their flexible spines are one of the main reasons they are able to behave in this manner. This increased mobility unfortunately means that they can also be susceptible to injury. Whilst all dogs can potentially injure themselves some are at an increased risk due to their conformation (Daschunds, Shih Tzus) or work (agility dogs, gundogs, police dogs). The average pet dog can also experience skeletal misalignments by an acute trauma (a fall or from rough play) or by a chronic build up (repetitive activities such as jumping in and out of a car on a daily basis, or playing with tug toys/balls or sticks).
