The Canny Company makes the Canny Collar, a headcollar designed to help you train a dog not to pull. Its giant-breed version, the Colossus, has the lead attach behind the head, so the noseband stays put instead of riding up towards the eyes.
A headcollar is a training aid, not a quick fix, so introduce it gradually and reward loose-lead walking. The leads cover training and everyday use: a double-ended training lead with eight configurations, a long line for recall practice, a wipe-clean waterproof lead and the Connect lead with a lockable handle. Prefer a body-worn option? See harnesses, or compare with other dog leads.
