We write on the heels of a long weekend layered with dogs and fun.  The National Dog Show, which you may have watched on TV yesterday, is held about ten minutes from our house, and a fabulous corded Standard Poodle named Joel, who just happens to be “family” (he is the sire of our gorgeous puppy, Luca) won Best of Opposite Sex two days running (and stayed overnight with us).  And two out-of-town handlers we know unexpectedly needed a place to exercise their charges, so we twice got to stand in our back yard while no fewer than seven show dogs, from ten pounds to 150 pounds, swirled around us.  We can’t imagine being much happier.

We are trying very hard not to bore everyone silly with endless discussion of our puppy-to-be, almost certainly interesting only to us.  But we are failing.  So, briefly, we comment that we met the whole spectacular litter last week – eight gorgeous butterballs. Five are white, and three are now black but will probably end
