A 6-year-old, spayed female Miniature Pinscher dog with chronic vomiting lasted for 7 weeks was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. Physical examination, complete blood counts, serum chemistry, gastroscopy, upper gastrointestinal series, endoscopic biopsy and histopathological examination were performed for the diagnosis. The complete blood counts and serum biochemistry revealed no remarkable effect to the patient's general condition. Gastroscopy revealed erosion, erythema in mucosal surface of gastric lesions and endoscopic biopsy performed. No significant findings in upper gastrointestinal series were observed, and histopathologic examination revealed infiltration of lymphocyte in the gastric mucosa. Based on these findings, the dog was diagnosed with lymphocytic gastritis. The dog were treated by metronidazole and ranitidine with hypoallergenic diet, and then the patient showed no vomiting or other complications.

A miniature schnauzer (8 years old, male castrated), diagnosed as diabetes mellitus 6 months ahead, were referred to the Veterinary Medical Teaching Hospital of our University with hindlimb stiffness, facial rubbing and tetany. Serum chemistry showed severe hypocalcemia, hypomagnesemia, and measured iPTH (intact pharathyroid hormone) concentration was low (less than 3.0 pmol/L). Consistent rate injection of calcium gluconate (282 mg/kg over 30 min) resulted in prompt relief of the tetany. Then typical treatment for hypoparathyroidism (calcium gluconate and dihydrotachysterol per os) with magnesium administration could control the neuromuscular signs. Diabetes mellitus is being controlled by insulin therapy and prescription diet. Hypomagnesemia in diabetic dog may be induced hypoparathyrodism.
