The Condo V/S the Dogs

Co-op boards in NYC are reputed to be notoriously sticky and exacting about whom they let in into the fold. Condo boards are often thought to be more lenient, now a Condo board on NYC's Upper West Side is trying to limit the number and the kind of dogs, owners have. New Yorker's real estate market has still not recovered from the recession and to have rules like this is silly isn't it? or is the board justified in passing these rules considering many apartment buildings in NYC don't allow pets at all ?
