Plain-English summary
A 7-year-old spayed female Shetland sheepdog suddenly started bleeding from her nose. After tests, the vet found she had Type III von Willebrand's disease, a bleeding disorder, and primary hypothyroidism, which contributed to her condition. Treatment with levothyroxine, a medication for hypothyroidism, helped normalize her hormone levels and corrected the bleeding issue. The dog is now stable and no longer experiences nosebleeds thanks to this treatment.

Abstract
A 7-year-old, spayed female Shetland sheepdog had sudden onset of right-sided epistaxis. Diagnostic tests revealed Type III von Willebrand's disease and primary hypothyroidism leading to an acute hypothyroid crisis and acquired factor VIII (FVIII) deficiency. Levothyroxine therapy normalized the serum thyroxine and FVIII concentrations. The delayed onset of disease and the reversible FVIII deficiency that was corrected with levothyroxine therapy, support a role for hypothyroidism in the pathogenesis of this dog's sudden bleeding tendency as has been seen with hypothyroidism in humans.
