Hi and welcome to EBN. Can you have Moobear over to your house to meet your son? Is the dog trained at all not to jump? The idea that bulldogs are lazy is really a myth. I have two who are three and four and they are quite active. They do sleep but they are quite interactive with the family for most of the day and love to play. I think having your son interact with Moobear first is the key to this being sucessful.
