Introduction

Dystocia is a common condition in dogs. It can be categorized as resulting from maternal, or fetal factors or most commonly a combination of both.

Objectives

To describe the presenting symptoms with the condition known as hydrallantois.

Methods

Pronounced abdominal distention, pale mucous membrane, tachypnea, and tachycardia were noted upon physical examination. Complete blood analysis, electrolyte and serum chemistry tests were done. Abdominal radiographs and ultrasound were performed to evaluate fetal status and size. Accumulation of fluid in the allantoic sac was revealed during ultrasound. Emergency caesarian section with panhysterectomy was performed and grossly, an insurmountable amount of fluid was noted in the allantois. Six neonates were extracted, four of which presented with anasarca.

Results

Hydrallantois is the result of the dysfunction of the placenta. It is more commonly observed in cows, ewes and mares, rarely in dogs and cats. Prognosis for future fertility of the bitch is poor and prognosis is guarded to poor.

Conclusions

Careful assessment of whelping patients must be done. Rectal palpation, ultrasound, and radiographs are useful tools in diagnosing this rare condition in dogs.
