Q. My dog is friendly off leash, but when we meet another dog on a walk, he barks and lunges. How can I stop him from acting out?
The behavior you are describing sounds like barrier frustration. Barrier frustration is distinct from aggression in that the canine is friendly toward other dogs when he is off leash, but is reactive when he is restrained by a barrier. The barrier can be anything from a fence or window to a leash. As with all behavior issues, the first step is a trip to the veterinarian to determine if there are any underlying medical conditions contributing to your dog’s behavior. Once your dog has been given a clean bill of health, it’s time to start training. In the case of barrier frustration, training should start as soon as possible, as reactions toward other dogs can intensify over time.
Teach Your Dog to Relax
Begin by teaching your dog that the sight of another dog means good things will happen. Employ your dog’s favorite doggy friends for these practice sessions, and keep all dogs on leash while you are training. Once your dog has mastered the basics, you can begin to expose him to strange dogs while on leash, either at a dog park or in your neighborhood. Start with the other dog far enough away that your dog notices him but does not react. Each time your dog looks at the other dog without barking or otherwise reacting, mark with a “good” or a click and treat. When you first begin, your dog will likely be nervous when he sees the other dog and he may only turn toward you for a moment, to get his treat, before looking back at the other dog. Treat frequently in the beginning, until your dog learns to relax. Once your dog can look at another dog without reacting, teach him to turn and sit facing you when you stop on a walk. Reward your dog for staying in his sit, or for maintaining eye contact with you, while the other dog passes by. Next, teach your dog to heel on leash as he approaches the other dog. Hold your dog on a loose leash; a tight leash can heighten reactivity. Treat your dog when he walks next to you; if he pulls on the leash or crosses in front of you, stop walking. Use a treat to lure him back to your side. Walk toward the other dog at an angle or perpendicular to the other dog, rather than head on. After a series of successful approaches, reward your dog with an off-leash play session in a safe area. In addition to teaching your dog to heel, teach him to turn with you on cue. Work on both a 90-degree turn and a 180-degree turn. Give your dog a cue, such as “turn” and lure him towards you. As soon as he turns, treat and continue walking forward rewarding the heel. A turn can be used to create distance between your dog and another dog, and allows you to focus on calming behaviors until your dog learns to relax when another dog is nearby. You can divert your dog’s attention by walking up a driveway, crossing the street, or moving behind a barrier such as a parked car or bush. Finally, turn spotting another dog into your canine’s cue to do a trick he enjoys. Excellent replacement behaviors include hand targeting, down stay, shake, spin, roll over and play dead.
Tools and Strategies
Certain cues may be causing your dog to react when he’s on leash or behind a barrier. The sound of approaching dogs, such as jingling tags or vocalizations, may set your dog off. When you are walking with your dog, you may inadvertently jerk or tighten the leash when you get nervous about an approaching dog. These cues make your dog even more tense. Change your dog’s association by pairing these cues with something pleasurable. Practice tightening the leash and giving your dog a reward. Pair the barking or collar jingling of another dog with the onset of a treat party. Extra exercise outside of training situations and away from other dogs, such as treadmill workouts or fetch, can also be helpful for dogs with barrier frustration. Dog-friendly canines can benefit from a play session with another dog before training to satisfy their desire for interaction. In addition, using food puzzles instead of food bowls to feed your pet helps to channel his extra energy. A Thundershirt can be extremely beneficial in training dogs with barrier frustration. Adding the pressure wrap shirt to a training session automatically calms many anxious canines. Collars are not the best solution for dogs that react on leash, because they don’t allow you to pull your dog around to face you when needed. Instead, use a harness that clips on the dog’s chest, or a head halter for optimal control. In an emergency, if your dog becomes overwhelmingly worked up at the sight of an approaching dog, you can distract him by tossing treats on the ground for him to pick up until the other dog is past.
