Do dogs know they're living? They act differently as they age, but do they realize that they used to jump up and down when their master came home? Or wag their tail instead of lying as flat as possible? How long is dog memory? Would they recognize a previous owner five years later?

“I'm sure she'll miss you,” the veterinarian responded.

The attendant walked around the counter to retrieve Daisy, who was still confined to her Gentle Leader. Those without dogs assume it's a muzzle, and those at the dog park wish that it were. What the Gentle Leader allows you to do is attach a leash underneath the dog's mouth, so that when fifty pounds of muscle charges for an animal, vegetable or mineral, the head turns away and the mad rush stops on a dime. Hey, free money!

Anyone walking Daisy with an ordinary leash should expect the kind of injuries typically associated with concrete skiing: skinned knee, chipped tooth, loss of limb. However, something magical happens when you strap Daisy into the Gentle Leader. She transforms into a completely different dog, a manageable dog, like a person with Tourette's Syndrome only using the words “darn” and “heck.”

The attendant removed Daisy's Gentle Leader like it was a decoration, thus releasing the genie from her bottle. Daisy leapt a good six feet in the air and stared eye to eye with the attendant. Meanwhile, I filled out the doctor's paperwork.
