Dog and cat shows

I've never been to a dog or cat show and I would love to (at least just as spectator :) )! But I have no idea where and when these shows are held in Montreal. Any suggestion? Thanks!

Usually both are at place bonaventure:
LE NOËL DES CHATS
From Friday, December 02, 2005 to Sunday, December 04, 2005
Open to the public

The dog show may be November 25, 2005 to November 27, 2005 but I am not sure... I can't find it yet (probably too early).

The large dog show is in November. There are other smaller shows throughout the year.
