A Martingale collar can help with dogs that tend to pull on a leash. This type of collar has a loop that shortens when the dog pulls, giving him an uncomfortable feeling, and loosens up when the dog stops pulling. It should be noted that this type of collar is not intended to choke your dog as long as it is properly fitted. The most common use for this collar is when training a dog for a specific behavior and is even used for show dogs.
It’s important that your dog knows proper leash etiquette before going on a walk. You can practice inside your house or in your backyard. Your dog should know and be familiar with the length of the leash. Practice walking and if your dog tries to pull on the leash, stop walking and call him back to you and reward him with a treat. This will help to teach him to stay close to you when he is on a leash. Once your dog knows to stay close to you while walking, try suddenly changing direction. Your dog will learn to focus on you while walking and not the surroundings, which can easily distract him. After awhile, you’ll notice slack in the leash and may even be able to walk your dog without holding the leash. The main goal is to have your dog be relaxed during the walk and to not pull on the leash if he gets distracted by something.
Keep in mind that your dog won’t be fully trained overnight. It will take some time and if the two of you keep at it, the end result will be much enjoyable.
