CONGRATULATIONS TO MASON FOR BEING THE PUPPY OF THE DAY!!!
I immediately recognized him and just knew you would be so pleased. There is no rhyme or reason in the way, as far as I can tell after these many years, of which dogs are chosen and when. What a lovely "belated" 4 month old Birthday gift for Mason!
Not every dog that is submitted is chosen as a Puppy of the Day, or Grown Up Puppy of the Day. I think the devil is in the details insofar as the better quality photos, the more likely to be chosen.
Mason is a huge hit!
