Just wanted some opinions on my 9 month old Dobermans play with other dogs. We take her to an off-leash park where many of the dogs enjoy grabbing at each others neck with their teeth and play fighting. To me, this seems violent and I like to discourage her from playing with other dogs this way, although many owners cheer on their dog. This is probably natural puppy behaviour but it scares me that some day she'll try to play with a child in this manner. Should i remove her from dogs who play this way or just let them play?
