ONE SMART DOG...

"I had a dog that was the epitomy of intelligent. Never was trained. Insisted on being a terror as a puppy. Learned hundreds of commands without pavlovian prompting.Indeed exhibited sensory arrays that defied reasoning, and this went beyond olfactory stimuli. Partner slowed when the cancer and came, and on the day we decided his suffering was impossible, it was spring, the chamise in bloom, and we went for one last walk. But that is another story."
