Lameness is an inability to properly use one or more limbs due to pain or weakness. The most common causes of sudden lameness in dogs are soft tissue injury (strain or sprain), injury to a joint, bone fracture, or dislocation. Your veterinarian will determine the best course of action based on your pet's condition, a detailed examination, and the results of diagnostic tests. Definitive diagnosis of the cause can be difficult. In some cases, a trial with anti-inflammatory medications and rest may be necessary.

Laryngeal paralysis is a condition that causes dysfunction of the larynx causing reduced ability to breathe deeply and can obstruct the airway. It can be a congenital condition of young dogs or may be due to a neuromuscular disease in older dogs. Clinical signs include coughing, noisy breathing, and exercise intolerance. A definitive diagnosis is made through an examination of the larynx with an endoscope or laryngoscope. Treatment of mild cases involves environmental management to reduce any stress on the larynx and medications used for flareups. More severe or congenital cases require surgery.

Laser surgery is a procedure that generates a beam of light energy at a specific wavelength, resulting in the cutting of tissues. There are advantages of laser surgery when compared to traditional stainless steel surgical scalpels, which are decreased pain, decreased inflammation, reduced blood loss, and improved tissue healing. Routine procedures such as ovariohysterectomy and castration are commonly done with laser.

Leaky gut syndrome refers to an increase in the permeability of the intestines. This condition may be caused by any significant insult to the intestines. Acute cases of leaky gut may be caused by infection, trauma, toxins, or medication overdoses. Chronic cases, in contrast, may be caused by food allergies, long-term NSAID use, or other causes. Your veterinarian will perform diagnostic tests to determine the underlying cause of your dog’s intestinal disease and treatments will be targeted at the specific underlying disease that is causing your dog’s leaky gut.

The femoral head is the ball part of the hip joint and if it develops necrosis or dies, it can no longer function properly. Necrosis is due to loss of the blood supply to the femoral head, which may be the result of a growth abnormality or trauma to the hip. It is a hereditary condition of small breed dogs. The most common clinical signs are slowly progressing hind limb lameness with a resulting inability to bear weight on the affected limb or both hind limbs. Diagnosis is made by radiographs of the hip joint. The treatment of choice is femoral head and neck ostectomy, which results in a good prognosis.
