The breed is predisposed to conditions found in many breeds, such as abdominal hernias. Westie puppies may be affected by craniomandibular osteopathy, a disease also known as "lion jaw", and is sometimes also referred to as "westie jaw". The disease is an autosomal recessive condition, so a puppy can only be affected by it if both its parents are carriers of the faulty gene. The condition appears across many breeds, including several different types of terriers, as well as other unrelated breeds such as the Great Dane. It typically appears in dogs under a year old, and can cause problems for the dog to chew or swallow food. Radiographic testing can be conducted to diagnose the condition, in which the bones around the jaw thicken; additionally, the blood may show increased calcium levels and enzyme levels. The condition often stops progressing by the time the dog is a year old, and in some cases can recede. It is normally treated with anti-inflammatory medications, and the feeding of soft foods. In some cases, tube feeding may be necessary. However, if the animal still cannot eat and is in uncontrolled pain, then euthanasia may be the only medical option remaining.
