Dear Editor,

Dr. Veenis’ point is well taken; ovariectomy is an alternative procedure to ovariohysterectomy in healthy, nongravid bitches. We chose the ovariohysterectomy procedure for our minimally invasive project because it is the more common procedure performed in the United States. ¹

Laparoscopic ovariectomy would be an interesting procedure to describe; however, it is possible that the complications of hemorrhage, cystic endometrial hyperplasia, and urinary incontinence would be of the same frequency and type in both minimally invasive techniques as they are in the open procedures. ² One disadvantage that ovariectomy might hold is that exposure to progestational compounds,

To test the predictive value of a doll and an artificial hand, reactions of dogs (n=100) were compared to histories of behavior toward children. Each dog’s reaction to the doll and the hand was categorized as normal, fearful, fearfully aggressive, or offensively aggressive. Sixty-five percent (n=37) of the dogs that had a normal or no reaction to the stimuli had a history of being good with children. Eighty-eight percent (n=34) of the dogs that had an aggressive reaction to the doll had a history of aggressive behavior toward a child. Dogs that were fearfully aggressive were significantly more likely to show fearful responses to the doll, and dogs that were either dominant or fearfully aggressive were more likely to exhibit aggression of the same type to the hand. The results of this study indicate that the doll and, to a lesser extent, the hand may be useful components in determining the aggressive tendencies of dogs. The results also point out the major limitations, because the false positives and false negatives are too frequent.

Electrocardiograms (ECG) from 35 dogs with subvalvular aortic stenosis (SAS) with a left ventricular outflow tract pressure gradient (PG) of ≥50 mm Hg were retrospectively evaluated for S-T segment depression (STD, ≥0.2 mV in lead II). Pressure gradient, age, heart rate (HR), and number of ventricular premature complexes (VPCs) on a 24-hour ambulatory ECG for dogs with STD were not significantly different from those for dogs without STD. The S-T segment deviation did not correlate significantly with PG, age, HR, or VPCs. The significance of STD in the dog with SAS remains uncertain. Long-term prospective studies are needed to fully understand this observation.

Overtly healthy Doberman pinschers, having moderate to severe myocardial failure secondary to dilated cardiomyopathy, which experienced ventricular tachycardia, syncope or collapse, and sudden death were studied to determine the effect of antiarrhythmic medication on their clinical outcome. Antiarrhythmia drug therapy may have retarded sudden death in 13 treated dogs compared to the six dogs not administered antiarrhythmia drugs.
