Dogs can have hearing loss due to increasing age or chronic ear infections, or they may be born with a defect. Deafness in dogs can present some challenges, but overall they can have healthy, normal lives. Training is still possible by making some modifications and incorporating hand signals. It is important to take their deafness into account when considering their safety and ensure that they are never off leash on or near a street.

Lumbosacral disease, or cauda equina syndrome, is caused by the narrowing of the spinal canal and results in compression of the spinal nerve roots; pressure on the nerves that exit the spine cause the clinical signs. This pressure may be due to a narrowed spinal canal caused by arthritis, intervertebral disc herniation, an infection in the disc, trauma, congenital malformation, or a spinal tumor. Dogs with lumbosacral disease are in pain. If the clinical signs and radiographs suggest lumbosacral disease, advanced imaging such as MRI or CT is recommended to make a diagnosis. Treatment involves either conservative medical treatment or surgical intervention.

A luxating patella is a kneecap that 'pops out' or moves out of its normal location. Signs include intermittent lameness, an unusual 'skipping' on the affected leg when the cat walks or runs, or difficulty jumping. A luxating patella can be corrected surgically, especially if the patella luxates frequently. If your veterinarian performs surgery before arthritis or another knee injury occurs, the prognosis is excellent.

A luxating patella is a kneecap that moves out of its normal location, causing an affected dog to skip or hop on three legs. Many toy or small breed dogs, including the Maltese, Chihuahua, French Poodle, and Bichon Frise, have a genetic predisposition for a luxating patella. Surgery should be performed to prevent the development of arthritis or another knee injury.

Lymphocytic plasmacytic gastroenteritis is a form of inflammatory bowel disease. While the exact cause is not known, it is possible that the intestinal bacteria themselves may be involved in stimulating the immune response. Signs include diarrhea, vomiting, loss of appetite, weight loss, and blood in the stool/vomit. Treatment may include nutrition management, immunosuppressive medications, and dietary supplementation of cobalamin, prebiotics, and probiotics.

Lymphoma is a cancer of the lymphocytes. Lymphocytes are cells that are involved in the immune system. Feline lymphoma most commonly affects the intestines; therefore, clinical signs of lymphoma are often similar to other intestinal diseases. Diagnosing lymphoma requires finding cancerous cells on microscopic examination. This cancer cannot be prevented, but the likelihood of a cat developing lymphoma can be decreased by preventing feline leukemia virus infection.

Lymphoma is a cancer of the lymph nodes and lymphatic system. This cancer may be localized to one particular region, or may spread throughout the entire body. Lymphoma is a relatively common cancer, accounting for 15-20% of new cancer diagnoses in dogs. The prognosis for lymphoma varies, depending on various characteristics that can only be determined by specialized testing.

Lysosomal storage diseases are a rare collection of conditions that are inherited. Many of them are more prevalent in certain breeds and are seen in the first few months of life. Clinical signs vary depending on the type of disease, but commonly include failure to thrive, incoordination, vision loss, and seizure. Prognosis is usually poor for long-term survival.

Bacterial overgrowth is a condition of the small intestine resulting in increased numbers of bowel bacteria. The major concern with bacterial overgrowth is the development of a condition called small intestinal bacterial overgrowth. The bacteria cause damage to the surface of the bowel so digested food cannot be absorbed resulting in malabsorption of nutrients. Malabsorption and SIBO both result in diarrhea but with bacterial overgrowth the diarrhea is chronic. Many cases respond to long term antibiotics.
