===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.<ref name=":0" /> Once the mutation is found in a dog, the dog should not be bred. This disease is caused by a lack of von Willebrand factor which plays a role in the clotting process of blood. This can cause abnormal platelet function and prolonged bleeding times. Affected dogs can be prone to nose bleeds, and increased bleeding following trauma or surgery. There are three types of this condition with Type I being the most common, while Type II and III being rarer, but more severe. Type I von Willebrand's disease is relatively common in the Scottish Terrier.<ref name="vonW">{{cite web|url=http://www.upei.ca/cidd/Diseases/clinical%20pathology/von%20Willebrand%27s%20disease.htm|title=What is von Willebrand's disease?|date=30 October 2001|publisher=Canine Inherited Disorders Database|access-date=2010-02-18}}</ref>

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]].<ref name="vonW" />
