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

INTRODUCTION
The urethra is a common area of urologic dysfunction in male dogs for conditions such as strictures, obstructive urolithiasis, rupture, neoplasia and incontinence. Examination of the male urethra is difficult and often requires a diagnostic imaging work-up. CT Urethrography (CTU) is a promising technique that we have developed.
OBJECTIVE
This study was undertaken to establish the diagnostic quality of CTU studies in the evaluation of the canine urethra.
METHODS AND MATERIALS
This is a retrospective case series. Medical records from the University of Edinburgh were reviewed to identify male dogs presenting with lower urinary tract symptoms receiving a CTU study under our protocol. Images were blindly reviewed scoring the quality of the study, number of CTUs performed and the urethral width at different levels (0– Collapsed; 1- Partially Filled; 2- Distended; 3- Stenotic; and 4- Obstructed) for transverse, sagittal and curvilinear studies. Results were correlated with the final clinical diagnosis.
RESULTS
21 male dogs with a diagnostic quality CTU study were included. Urethral width was scored similarly across different locations and image orientations. There was complete correlation between urethral width grades 3 & 4 and clinically diagnosed stenosis and obstruction. 11/22 dogs (50%) required 1 CTU study, 9/22(41%) dogs required 2 CTU studies; and 2/22 (9%) required 3 CTU.
CONCLUSION AND DISCUSSION
CTU gives an accurate assessment of the urethral
lumen in the male dog allowing reliable and time- efficient diagnosis of stenotic and obstructive conditions. Additional reconstructions in sagittal and curvilinear planes were helpful for the confidence of diagnosis, but did not change scoring results.
    OBJECTIVES
To describe the presenting symptoms with the condition known as hydroallantois.
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.
