An amusing story, although I'm a little concerned about where this continued blurring of the lines between humans and their animal companions is leading us. :)
The excerpt:
Despite the festive atmosphere, Admiral Boom, who
wore a bib patterned with Stars of David, spent much of the party under
the dining room table. 
n the long
walk of history between man and dog, the bark mitzvah could be seen as
an unexpected pit stop. Yet it was celebrated on Saturday night in the
Bronx in a traditional way, with a party for family and friends of the
13-year-old that included a chopped-liver sculpture, choruses of "mazel
tov!" (or, in this case, "muzzle tov!"), a cantor and gifts.
The proud father, wearing a dog-patterned tie, was Mark Nadler, 43, a New York cabaret singer. He had sent out invitations to dozens of friends "to share a special day in our lives when my dog, Admiral Rufus K. Boom, will celebrate his bark mitzvah in the tradition of our ancestors."
Mr. Nadler, who had his bar mitzvah years ago, said he was not unfamiliar with entertaining at bar mitzvahs at "high holy places like the Hard Rock Cafe." They sometimes seemed to be expensive productions that helped parents raise their social radar rather than sacred coming-of-age ceremonies for 13-year-olds. So Mr. Nadler thought he would give a bar mitzvah for his wheaten terrier and watch the eyebrows rise.
