Crazy shouldn’t work ever for puppies … but it does. And why does it? Because we accidentally reward it. An example is a puppy gets excited, squirms and squeals in your arms, bites a bit and you put her down. This is what the puppy wanted, they wanted out of your restraint, therefore we rewarded the behaviour by doing what the puppy wanted in the first place.
This type of rewarding inappropriate behaviour happens numerous times throughout the day, from pulling and acting out on walks, to witching hour in the evening. Take a step back and look at the “crazy” behaviours that you don’t like that you might accidentally be rewarding … and stop rewarding them.
The below is a quick video example of how not to reward the crazy in a specific circumstance.
