I don't teach or recommend so-called "purely positive" methods that allow misbehaving pups to continue misbehaving, instead of teaching them which behaviors are and are not allowed. "Purely positive" is fine for teaching tricks and high-level competition exercises, but NOT for teaching the solid good behaviors that all family dogs need to know, and NOT for stopping behavior problems such as barking, jumping, chewing, nipping, chasing, etc.
Every dog needs to learn to walk on a leash. Besides the fact that most areas have leash laws, there will be times when keeping your dog on a leash is for his own safety. Learn how to introduce your dog or puppy to the leash, then teach him how to walk properly on the leash, even beside you on a bike. A loose leash walk teaches your dog not to pull or lunge when on the leash, making the experience more enjoyable for both you and your dog.
Training clubs that run the Kennel Club Good Citizen Dog Scheme - the largest dog training programme in the UK are a sensible place to begin. Here you will learn about every aspect of dog ownership from the Puppy Foundation Courses through to Bronze, Silver and Gold award levels. Go to GCDS Training Clubs in your County to find one near to you or email the GCDS Team ([email protected]) or call 0207 518 1011.
