As I stumbled down the front steps at 3 a.m. today, Sherlock and Izzie straining ahead of me, the heat and humidity, even at that hour, were like a physical affront. The dogs had eaten 4-5 bananas between them, and we were both suffering the consequences. I was aware of my own grouchiness, and also of their irrepressible dogginess. They will always take advantage of a chance to eat any human food they can get their teeth into. They will never stop, look at each other, and think, Nah, remember when we ate those bananas?
