Michael...that was very very funny!!
Dog probably lives a wonderful life....I'd love to see what his wife looks like. But he did have that crush on that cocker spaniel in Negative Reaction...does that mean he was cheating on his wife?

-they both eat ice cream

-they don't follow orders/directions very well, remember Dog was ousted from obediance school?

-their "coat" tends to be slightly wrinkled and baggy

-they have very expressive eyes IMO

Good point!! If that were true, he's be very dissimilar to our hero. Columbo--like so many happily married men--seems embarrassed at the mention of sex. . . which I'm sure Dog is not.
