Only dogs that are taking part and have passes issued are allowed at Crufts. You can understand why when you consider that in the breed rings alone there are over 23500 dogs entered over the 4 days, adn that doesn't take into account all the oens doing Discover Dogs and special events.
Your dog would likely be overwhelmed even if he were allowed to go, so sould be better left at home for the day with a juicy bone and a freind or neighbour to come in adn let him out for you during the day.
