The 37 degree bitch "AH............." A long ear-piercing scream shattered the stillness of the night. One long scream from the cage where a bitch was warded after the removal of her uterus but not ovaries. A scream of death rarely heard. I rushed to the cage and pulled out the bitch. Put her on the consultation table and examined her mucous membranes. Her tongue was pale yellowish white. Pupils were dilated. This was the end. I should not have undertaken this high risk surgery. Middle aged and fat bitches are not good risks for anaesthesia. Their heart may fail any time. In addition, this bitch has a rectal temperature below the normal 38.5 deg C. It was 37.5 deg C at admission and dropped to 37.0 deg C. "Lots of dirty brown sticky discharge from her vagina. My bitch is having a miscarriage," Mrs Chan said. "Your bitch is in a state of shock," I said. This was the first time I was presented with the bitch. Singaporeans don't usually get medical check ups for their bitches although the women do have regular ones if they are pregnant. How could this bitch be pregnant when she was in the house all the time and there were no male dogs? "She escaped for one day," Mrs Chan said. "Around 3 weeks ago," Mrs Chan's maid confirmed. A one night stand? Can a bitch be pregnant when she left for one night? There is a veterinary medical condition called Misalliance.  It means that the naughty bitch had got mated and the British owner where I used to see practice in the early 1970s, would bring her to the veterinarian for an anti-conception injection which ought to be done within 24 hours of mating.
