Working dogs lose their sight to remarkably ordinary things: grass seeds, grit thrown off a track, wind at speed on the back of a bike. A visor across the eyes stops all of that, and a vented shell over the skull takes the knocks that come with dense cover and low branches. This is protective equipment rather than costume, and it only makes sense if you have a genuine reason to need it.

The shell is vented, which is what makes it wearable at all, since a solid helmet on a dog would simply become a heat trap within minutes. The goggle visor is clear and shatter-resistant, so a flying stone stops at the lens instead of breaking into the eye behind it. An adjustable chin strap holds the whole assembly in place at speed, and the ear covers are removable, which is how one product ends up fitting both a broad-headed dog and a narrow one. Two finishes are offered, black and mud colour.

• Vented hard shell with a clear, shatter-resistant goggle visor
• Adjustable chin strap
• Removable ear covers
• Two colours: black and mud
• Intended for medium and large breeds

Be honest with yourself about this one. Whichever it turns out to be, no dog accepts headgear on the first attempt. Build it up over short sessions with food, and never leave a dog unattended while wearing it.

Who it's for: Handlers of working or high-speed dogs who genuinely need eye and head protection, rather than owners who like the look of it.
