Just like humans, dogs sometimes break bones, sprain muscles, slip discs or tear ligaments, all of which can lead to the sudden onset of limping or movement difficulties. Torn knee ligaments occur frequently. Muscle strains are less common, but even these can occur while dogs undertake something as simple as climbing stairs.
Arthritis (sometimes referred as osteoarthritis) can also present as a sudden onset of lameness, should a jarring or untoward movement occur. Of course, dogs may chronically suffer from illnesses of lameness as well. Diagnosis and management of these conditions, however, will not be addressed here.
What To Watch For
In most limping cases there will be no external sign of damage. However, limbs may dangle at an unnatural angle when fractured or dislocated. Bones may even pierce the skin. Sometimes bleeding as well as swelling may also occur.
Accidents and other traumatic origins are the most common causes, though slow, chronic degeneration of a ligament or disc, for example, can sometimes lead to a sudden onset of orthopedic pain or lameness.
