Definitely not laughing at these antics as could cause injuries to kids
and/or other dogs (even if accidently) and she could be put down.
This is prime time for teaching her that humans ALL are alpha and to
be respectful to all who share the home. Yes, she's a puppy and she
probably will calm down in another year, can you afford to wait that
long and hope there's no injuries happen? Hopefully others have some
great training tips that have children. Mine are grown and my dogs are
taught what is tolerated & what is not, all along the way. Most of my
breeds have been very alpha, I have no problems as I am MOST alpha.
