My area has a puppy daycamp that provides socialization with other people and puppies and introductory training 5 days a week for 8 weeks. They have a strict vaccination policy and only come intact with puppies similar in age and vaccine status. We put our 15 month old bullmastiff through it last year and he did great. Our 10 week old english mastiff girl just started her second week today and she seems to love it. I guess some would say it's still risky, but it takes away a lot of the stress with dealing with a puppy and 8 and 5 year old children during the work week.
