It is extremely important to do what's best for your dog's health, comfort and safety!
While you’re teaching your dog not to pull, you should use a six-foot leash. Use whichever width and material that feel comfortable to you. Extendable leashes, such as the Flexiä, or leashes longer than six feet in length are great for teaching re-calls, but they don’t work well if you’re trying to teach your dog not to pull on leash. and it could also be a safety hazard.
Regular buckle or snap collar
Martingale collar (also called a limited slip collar or greyhound collar)
Head halter/head collar (such as the Halti®, the Gentle Leader® and the Snoot Loop®) Please note that these are only suitable for Options One and Two. Serious injury could result if they are used with punishment methods using leash jerking.
No-pull harness (such as the SENSE-ation®, the Easy Walk® or the LUPI®)
They are effective tools, making walks more pleasant for you and your dog.
