Biting and Aggressiveness
One last issue in dealing with dog training is a generic one that comes up with any dog breed...biting and aggression. Whether your Schnoodle bites you or someone playfully or aggressively as a defense mechanism, you need to establish a sort of "heel" command to stop him/her.
My husband and I use "Be Nice" with Toby when he starts to play too roughly or starts acting aggressively towards another person. You could also use the classic "Heel". It's really up to you, but just be consistant so your Schnoodle does not get confused.
