Dog is attacking my parents!

My mom has been raising a rottweiler and she's getting pretty big (the dog). Whenever my mom calls her over to play with her, the dog will jump on her legs and refuse to let go!. This is fine for now, but when she grows bigger, it will definately be a big problem. What can she do to solve the problem?

Stop letting him jump up! Change how she plays with him. Maybe use a different training method...

This puppy needs to be in training class immediatley.

This problem will only escalate if it's not dealt with.

Please help her find a training class and get enrolled.
