For effective leash training, you’ll want to make sure you have both a shorter leash and a longer leash. Short leashes are about six feet long, and long leashes are about 25 to 30 feet. Leather leashes are more comfortable, but nylon leashes are more durable. \n2. __Penny bottle__. Take an empty water bottle, remove the cap, insert a handful of loose change, and recap the bottle. This training method is useful when teaching the off command and for bark control. \n3. __Dog training clicker__. Training clickers emit a distinctive clicking sound when pressed. By triggering a click while simultaneously teaching a technique or offering a treat, you can condition your dog to associate the sound with the command or reward. This, in turn, can help reinforce their training. Clicker training can be especially useful for the come command.\n4. __Lure stick__. These dog supplies are adjustable rods with a clip at the end for holding treats. They’re particularly helpful for training dogs that are smaller in size. \n5. __Martingale collar__. Martingale collars use two connected loops to progressively decrease the size of the opening around your dog’s neck. When your dog’s not pulling, the collar fits nice and loose. As they pull, the collar tightens to prevent their heads from slipping out. Martingales are considered more humane than choke and prong collars.\n6. __Gentle Leader headcollar__. The Gentle Leader is an alternative to a traditional dog collar. Designed to attach to the dog’s snout, the collar sits high on your dog’s neck and spares painful yanking on their trachea.\n7. __Easy walk harness__. Harnesses attach around your dog’s body rather than around their neck. This dog harness can be especially useful with small dogs, whose necks can be susceptible to whiplash. \n8. __Plastic cones__. Simple plastic cones can help direct a dog’s walk and be useful for teaching the heel command.\n9. __Treat bag__. Dog treat bags are specifically designed to hold your dog’s favorite treat. Try attaching a treat pouch to your belt or wearing it over your shoulder for easy access. Having easy access to training treats can make it easier to reward your dog for performing tasks or good behavior. \n10. __Notebook__. While pet training, use a notebook to keep track of your dog’s training progress. Draw out a simple chart to keep track of your dog’s success with each command day after day.\n\nYour dream of having a dog who understands words like “sit,” “stay,” “down,” and—crucially—”no” is just a [MasterClass Annual Membership](https://www.masterclass.com/) away.
