A 2024 UK study found a life expectancy of 12.7 years for the breed compared to an average of 12.7 for purebreeds and 12 for
crossbreeds. Two genetic health concerns seen in the breed are
von Willebrand disease (vWD) and
craniomandibular osteopathy (CMO);
Scottie cramp,
patellar luxation and
cerebellar abiotrophy are also sometimes seen in this breed. Common eye conditions seen in a variety of breeds such as
cataracts and
glaucoma can appear in Scotties as they age. There are no specific conditions relating the skin that affect the breed, but they can be affected by common dog related conditions such as
parasites and
mange.
Cancer in Scottish Terriers Scottish Terriers have a greater chance of developing some
cancers than other purebreds. According to research by the Veterinary Medical Data Program (1986), six cancers that Scotties appeared to be more at risk for (when compared to other breeds) are: (in descending order)
bladder cancer and other
transitional cell carcinomas of the lower urinary tract;
melanoma;
gastric carcinoma;
squamous cell carcinoma of the skin;
lymphosarcoma and nasal carcinoma. Other cancers that are known to commonly affect Scotties include
mast cell sarcoma and
hemangiosarcoma. Research has suggested that Scottish Terriers are 20 times more likely to get bladder cancer than other breeds and the most common kind of bladder cancer is transitional cell carcinoma of the bladder (TCC). Typically symptoms only show when the particular dog is under some degree of stress. The front legs are pushed out to the side, the back arches and the rear legs overflex, causing the dog to fall should it be moving at speed. The condition is not seizure related, and the dog remains conscious throughout the event, with symptoms abating once the cause of the stress has been removed. Currently, there is no known
genetic testing available for Scottie cramp. A diagnosis will come from a veterinarian once diagnostic tests have been conducted. Diagnostic tests for Scottie cramp, include a physical, complete blood count, a biochemistry profile, and a urinalysis. Although Scottie cramp is an inherited disease, it is a non-painful, non-life-threatening, episodic disorder. Affected dogs with Scotty cramp and their litter mates should not be bred, otherwise this disease can be passed to any future offspring they may have.
Vitamin E,
Diazepam and
Prozac have all been shown to be effective treatments should it be required. Scotty cramp is found in other breeds of terrier, including the
Cesky Terrier.
Craniomandibular osteopathy Craniomandibular osteopathy, commonly known as "Lion Jaw", "Westie Jaw" or "Scottie Jaw", is caused by excessive bone growth in the mandible, usually occurring between three and six months of age. It is an autosomal recessive hereditary disorder, and can limit the ability of a dog to eat and drink. The Scottish Terrier is one of the more commonly affected breeds.
Von Willebrand's disease Von Willebrand's disease is a hereditary bleeding disorder found in both dogs and humans. DNA testing used widespread by what are known as reputable breeders, has caused a huge decrease in affected dogs. Type I is more widespread in
Doberman Pinscher, but is as common in the
Shetland Sheepdog as the Scottish Terrier. The condition appears in most breeds to some extent, but other breeds with an increased risk include the
Golden Retriever,
German Shepherd Dog,
Basset Hound and
Manchester Terrier. ==Famous Scotties and popular culture==
