ABSTRACT
Two intact bitches aged 9 and 11â years were referred due to chronic polyuria, polydipsia, vomiting, anorexia and progressive lethargy. On clinical examination, signs of tissue overgrowth (large paws, widened interdental space, pharyngeal stridor) were noticed. Diabetes mellitus (DM) was diagnosed in one dog (case 1) and diabetic ketoacidosis (DKA) in the other (case 2). There were increased IGF-1 values suggestive of hypersomatotropism. Progesterone values and pathological findings of the ovaries and uterus indicated diestrus. Diagnosis of diestrus-induced hypersomatotropism was made and ovariohysterectomy was performed in both dogs. Dog 1 also had multiple mammary neoplasms treated with bilateral mastectomy. Treatment resulted in diabetic remission in case 1 and improved glycaemic control in case 2.â Overall, diestrus-induced hypersomatotropism is rare but should be considered in any intact diabetic bitch with acromegalic features. Ovariohysterectomy is recommended and associated with a fair to good prognosis.

An 8-year-old male Australian Shepherd was presented with bleeding from the lip and hemoabdomen. Hematology demonstrated marked thrombocytopenia and anemia. Abdominal ultrasound followed by laparotomy did not detect the cause of bleeding. Plasma transfusion resulted in temporary stabilization. Severe von-Willebrand factor deficiency and factor-VIII deficiency were diagnosed. After subsequent bleeding episodes, infection with Angiostrongylus vasorum was found in both a fecal parasitological examination and by PCR from EDTA-blood. Following successful therapy with fenbendazole, von Willebrand factor and factor VIII were within the normal range. This is the second case report of an acquired von-Willebrand-factor deficiency associated with Angiostrongylus-vasorum infection in a dog, and the first case report with concurrent factor-VIII deficiency.
