The truth is: If it is the law and you allow your dog off leash, you are breaking a law. In a civilized society, members do not simply pick and choose which laws apply to them. I repeat this mantra: It does not matter that you perceive your dog to “be friendly” or that “he loves other dogs.” It does not matter because the dog you have no voice control over is hurling himself into the faces of dogs who very well may NOT be friendly to other dogs. Your dog galloping right up to a leashed dog is rude canine behavior, even if you are running behind your dog screaming: “Don’t worry! He’s friendly!!” You endanger your own dog and all those you allow him to terrorize or bother.
Teach a cue. Introduce your puppy to a sound cue that means, “food is coming.” Some people like to click and treat, some people use a word like “yes,” and some people cluck their tongue. Whichever you use, the method is the same: In a quiet, distraction-free area, with the puppy on a leash and collar, make the sound. The second your puppy turns toward you and/or looks at you, reward him with a treat. After a few repetitions, you’ll notice your puppy not only looking at you, but also coming over to you for the treat.
