Do Shiba Inus have health problems?

1. Hip and Elbow Dysplasia: Hip and elbow dysplasia are two of the most common skeletal diseases seen in dogs. They are similar diseases in which either the hip or elbow joint has grown abnormally or is misshapen. The abnormal shape prevents the joints and sockets from properly meeting one another, resulting in rubbing and grinding instead of sliding smoothly. Unlike in hip dysplasia, where the main problem is joint instability, the abnormalities seen in elbow dysplasia often result in pieces of bone and/or cartilage breaking loose and irritating the joint tissues. 

1. Patellar luxation: Also known as slipped kneecaps, patellar luxation is a common problem in many dog breeds. It occurs when slight abnormalities cause the knee joint to slide in and out of place. This can cause pain and occasional lameness. Surgical treatment is available for severe cases, although many dogs lead normal lives without treatment.

1. Chylothorax: Chylothorax is a condition that results from fluid building up in the chest cavity. The build up usually happens when a digestive fluid called chyle leaks into the chest cavity and causes excessive pressure on the chest and its organs. This accumulation causes difficulty breathing, decreased appetite, coughing, and lethargy. Treatment includes removing the fluid, diet changes or, in serious cases, surgery.

1. Eye Disorders: The Shiba Inu is prone to cataracts, glaucoma, and Progressive Retinal Atrophy (PRA), which can eventually lead to blindness.

1. Others: Cancer, hypothyroidism, and allergies also affect this breed.
