TIP #1: DON'T PUNISH A GROWL
It's very common for dog owners to punish their dogs for growling. Unfortunately, this often suppresses the growl – eliminating his ability to warn us that he's about to snap, literally and figuratively. On other occasions, punishing a growling, uncomfortable dog can induce him to escalate into full-on aggression.
Growling is a valuable means of communication for a dog - something that dog owners should appreciate and respect rather than punish.

TIP #2: REWARD vs. REINFORCEMENT
Reinforcing a behavior is different than rewarding it. Rewards don’t always work - anyone who’s ever been an employee anywhere can think of an example to support that. But reinforcers always work - because by definition, a reinforcer is anything that, as a consequence of a behavior, increases the future of probability of that behavior. If a reward doesn’t have that effect, it’s not a reinforcer for that learner.
