Megaesophagus in Littermates Dogo Argentino Accompanied With Hypothyroidism

Abstract

Four littermates aged 5 years, belonging to the Dogo Argentino breed, experienced frequent
regurgitation, and bilateral alopecia. The diagnostic approach of treatment was associated with
a clinical examination of thoracic and abdominal plain, using a contrast radiograph and by
performing esophagogastroscopy. Skin scrapings of the affected dogs were examined microscopically to exclude any discrepancies in the observation due to parasitic infestations. The
serum levels of T4, T3, and thyroid-stimulating hormone (TSH) were estimated. On the basis
on medical history, clinical symptoms, reports of thyroid profile, radiologic and endoscopic
findings, the dogs were diagnosed with megaesophagus concurrent with hypothyroidism. Oral
administration of thyroxin and assisting feeding on a raised table was prescribed. The dermatological signs and regurgitation improved significantly with continued feeding on.small multiple meals with a high calorie content accompanied with elevated feeding for management of
megaesophagus, proton pump inhibitors Controloc® 20 mg pantoprazole tablet per day for the
long-term management of gastroesophageal reflux and gastric hyperacidity, in addition to oral
levothyroxine for cure of hypothyrodism using Forthyron® 0.8 mg pills dosed at 20 μg/kg every
12 hours for three months.
