Dogs go on the bills

Last time I bought postage stamps, I purchased two sheets of the Adopt a Shelter Pet. On it, photos of adopted cats and dogs alternate. What particularly caught my eye was a dog which looked like a friend of mine's and a cat who favored my Pyewacket.

But I didn't want to send "Pye" on a bill, so I decided that bill payments would get a dog stamp and personal items a cat. In fact, on those that Pye graced, I even write "Pye says hi" beneath his face. Now, as to whether or not the recipient sees that is another matter.

But I find I'm running out of dog stamps. I must pay too many bills or not write enough letters.
