The other day I was working with a client whose dog had a ‘bad’ habit of pulling really hard on a leash to greet oncoming people. It is actually not an uncommon behavior problem that I get called upon to help with.
On that appointment, over the course of one hour with numerous short sessions, that same dog learned to stay at his owner’s side with a loose leash while I walked up to pet him. Much more work will be needed with different people in different settings but the learning process was begun.
