These collars are quite popular, they are used mainly for large, uncontrollable strong dogs. I have used both the Halti and Gentle leader with two very large rescued dogs and the dogs walked well. But there are very few dogs that will tolerate them and it takes an introduction period and training for acceptance. Most dogs paw at their face, shake their head and roll around to get out of it. The dog pictured has a long muzzle, so it does not sit right under his eyes but most do and it can’t - shouldn’t be used on short-muzzled dogs. The dog’s muzzle is very sensitive and has an abundant nerve supply, so the strap across the nose ought to be padded.

This equipment is supposed to be used gently as a guide, not to be pulled or yanked as they can cause damage to a dog’s neck and spine if the dog lunges, or it pulls hard on the lead. It is also best to avoid meeting other dogs while wearing it, and they are meant to be used for walking only. Many dogs I see wearing a Halti appear suppressed, similar to dogs experiencing non-contingent punishment. Because dogs delight in following their nose, sniffing out scents, stopping to “smell the roses” halters make it uncomfortable, sniffing is what makes walks fun for them. The Halti should be a training tool while learning to understand and respond to words and commands with rewards, to not pull. Ideally, in the long term a Martingale collar ought to be sufficient, or a non-pull harness, these two I use together when walking, the harness for comfort and the Martingale collar for more control if needed.
For the horse, the halter sits well down on the long bony part of the muzzle, far away from the eyes, not just under the edge. The canine head does not readily lend itself to haltering. For centuries people have used collars and harnesses for dogs, reserving halters for animals better suited to it.
However, the Halti for dogs is seen by many trainers as positive and humane. In some situations, head halters may be a suitable choice, but it should be viewed as a temporary phase, not a life-long solution.
