What causes shaky legs?

I recently had a question about what can cause shaking, especially in the legs of an older dog.  The most common cause of shaking legs in the young dog that I see is fear- these are dogs that do not want to be in the examination room! But for the older dog shaking at home, muscle weakness is often the root cause. Several systemic illnesses can result in muscle weakness. Kidney disease often causes loss of muscle tissue as well as imbalances in the electrolytes, various minerals that are essential for muscle function. Adrenal gland disease can also cause muscle loss and electrolyte imbalances. Cancer must always be on the list as well, due to the unpredictable nature of the disease. Systemic disorders are diagnosed with blood and urine testing, sometimes x-rays and ultrasound as well, usually on an outpatient basis. Therapy can include dietary modifications, mineral supplementation and physical therapy, as well as medications where needed.

Pain from arthritis is an often unrecognized factor in shaky legs and muscle weakness. When it is more difficult to get up and move, your pet exercises less, and muscles gradually atrophy. While leg joints such as hips, knees and elbows are often affected, don’t forget all the joints in the back. As many of us know, when the back hurts, everything hurts.

Acupuncture and cold-laser therapy are the basic tools that I utilize for my patiens with arthritis. Prolotherapy and stem cell therapy very successful, but are more “invasive” interventions, and must be done with sedation or anesthesia, so are not suitable for all pets. Massage is wonderful because it is usually available from travelling therapists who will come to your home. Some massage techniques are also very easy to learn to do yourself, and are a special close bonding experience for you and your dog or cat. Herbal and nutritional interventions such as high levels of omega-3′s from fish oil, green-lipped muscle extract, cucurmin (turmeric extract), MSM, glucosamine etc. can be very effective in reducing the pain and mobility restrictions of arthritis. Physical therapy is also a very valuable part of a multi-modal approach to arthritis, to help strengthen muscles and the tissues that support the joints.
