It's ok to try to train your pets.

Kam takes the dog to an obedience course, and it learns to behave well.
Kam decides to keep the dog on a leash at all times in the park, so it can't run off.
The dog sees a squirrel, and acts as if it wants to run, then obey's Kam's command to heel.
The dog tries to run after a squirrel, jerking the leash so hard that Kam gets a sprained wrist.
