Mary is right-the younger the puppy, the more likely you are to get thrown out with it.MaryAndDobes said:
Another thing to consider is you want to provide only positive experiences when you're socializing young puppies, and you can't control how other dogs in a crowded situation (especially indoors) are going to respond. One ugly incident, and you could wind up with a puppy that's afraid of other dogs.
So while I've taken young pups to shows in the past, it's not something I do anymore...they really don't belong there.
