Couldn't spell 'walk' in front of our last dog, she knew what it meant and would get excited enough to start knocking things over in her rush toget out.
They're not nearly as perceptive as reptiles, who are smart enough to stay out of your damn way and not shed like a banshee whenever they traipse around your furniture.
The dog I had growing up, a mutt, was the exact same way. You couldn't spell the word 'walk' without him going nuts. He was the same way with the word Moped. I would take him for rides on my Spree (what a site to see!) and I couldn't say or spell the word without him heading to the actual moped to get ready. Riding on the moped was his favorite thing in the world...
