Well you can take your dog in if you enter the Companion Dog Show adjacent to the main showground.
You will however have to fill in a special events entry form stating that your dog is vaccinated and hasn't beein in contact with any infections etc as in a normal CH show entry.
Only prob is entries aren't being taken until 12, so it depends what time judging for pugs is. (And obviously your dogs can only be entered in the companion dog show, not the main show.) Sorry had to point that out as people have rung and asked that very question!!!
