I agree with that policy.. Too many people think "ooh lets get a puppy for xmas".. Then a few weeks later they don't want the responsibility it entails looking after them .. So not fair on the pet... :0(
i think it's a great policy too. Folks do get caught up in the fun and glee and what's more fun and glee than a puppy? Then comes the reality and, as you say, no prior thought to the commitment required. If shelters close for the season, less puppy-grabbing.
