The 8 initial signs of Degenerative Myelopathy (DM) in dogs often manifesting gradually and can be subtle. Common early signs of DM may include:
-
Mild Gait Abnormalities: Dogs may exhibit a slight, often asymmetric, dragging of their back paws when walking. This is reffered to as posterior paresis. This may be more noticeable on smooth or slick surfaces.
-
Difficulty with Balance: They may appear ataxic which is an unsteady or wobbly gait. This may be particularly dramatic when trying to turn or navigate corners.
-
Muscle Atrophy: Thinning of the muscles in the hind, or pelvic limbs. Muscle atrophy can be particularly noticeable around the thighs, hips, and lower back.
-
Loss of Coordination: They may have trouble coordinating their movements, which can be observed when trying to stand up from a lying position.
-
Loss of Reflexes: Conscious proprioception deficits in the hind legs, also know as the "knuckling" reflex, may be diminished or absent. Worn nails can be an early sigh of a CP deficit.
-
Altered Paw Position: Dogs might have a wide based stance with their rear or pelvic limbs. This can be a compensation due to their hind limb weakness.
-
Slower Movement: Dogs may be slower to rise from a sitting or lying position, and their overall movement may become more deliberate. Dogs with DM may display a lack of endurance as well.
-
Difficulty Climbing Stairs or Jumping: Once easy tasks like jumping into the car, onto the couch or running up the stairs may become challenging over time.
Early signs can be indicative of various orthopedic or neurological conditions, and a definitive diagnosis of DM starts with a veterinary neurological examination. Specific tests like blood work, xrays/ radiographs, CT scan, or an MRI may also provide useful in making the diagnosis. If you suspect your dog may be showing signs of DM, consulting a veterinarian for a proper evaluation is crucial for accurate diagnosis and appropriate management.
