"Disconnect the general anaesthesia," I said to my assistant. I put the endotracheal tube into my mouth and blew air into her lungs three times and compressed her chest three times. A sweetish smell of anaesthetic gas came out of the Maltese mouth. She was responding slowly. Her breathing started.

The rest of the surgery was uneventful as the dog breathed regularly. I incised the skin about 2.5 cm from the umbilicus. I could see the dark brown lobes of the liver. I inserted the spay hook and hooked out the left ovary. I thanked the owner for presenting a female dog that was not on heat. Spaying a female dog during heat was risky as there would be much bleeding as the fragile blood vessel and womb tissue break when clamped by the artery forceps. Lots of bleeding and maybe death later. But this case was a dream boat. No bleeding.
I reduced the anaesthesia to 0.5% and then to zero 5 minutes before the end of surgery. This was a thin Maltese weighing around 3.5 kg and the usual 2% maintenance dose was not necessary. The Maltese woke up 2 minutes later as if she had a nap.
At 5 p.m, the young lady owner came to pick up the Maltese. I had some time to do some research on how Singaporeans keep dogs and invited the lady to sit down and talked about the subject she loved most, besides her husband.
"How did you toilet-train your Maltese during the first week?" I asked.
"It was so long ago," she said as she took out the puppy papers from a folder. "I put newspapers covering the whole floor of the kitchen and the bathroom nearby. Then I removed the newspapers gradually till only the bathroom had newspapers. I want the puppy to eliminate in the bathroom."
"How long did you take to successfully paper-train her?" I presumed she had success in paper-training.
"Can't remember," the lady said. "Now she is 2 years and 4 months old. She goes to the bathroom floor near the kitchen to eliminate. My maid will then hose the urine away."
The lady made a surprising statement: "The Maltese purposely pees outside the door of the bathroom sometimes. Especially after midnight and when nobody is at home. But this would not be done regularly."
I thought: "This must be urine marking. Female dogs seldom do it but I am sure that some will urine marking. Maybe alpha female dogs?"
Yet this was the only spot that the Maltese would pee deliberately. As an adult dog, I presumed she would know better than to soil the place.
I put a piece of paper for the lady to sketch the floor plan of the bathroom and the kitchen and explained the routine of the Maltese.
Why would this Maltese behave so strangely, especially after midnight? She sleeps in the master bedroom but would never go the master bathroom. When she needed to pee, she would run out and just pees outside the door of the kitchen bathroom.
Why this unusual canine behaviour?
"I don't think there is much space inside the bathroom," I noted from the sketch and from my visits to the typical HDB (Housing and Development Board) apartment. "Most likely, the dog just did not want to dirty her paws by stepping into the kitchen bathroom which could be soiled with urine at, say, 9 p.m. Do you or your maid hose the bathroom before you go to bed?"
"Too tired to do that," the lady in her late 20s shook her head. She worked long hours as she climbed the corporate ladder of a famous multinational company.
