Why Dog Goggles matter

Most dogs will face some type of eye irritation, injury, or disease in their lifetime, especially active dogs exposed to wind, UV rays, or brush. Goggles provide critical protection for:

• Dogs with eye conditions like Pannus or Dry Eye
• Post-surgery or injury recovery
• High-exposure environments: sun, wind, dust, sand, snow, or trail debris
• Dogs who ride in cars, trailers, or sidecars
• Light-sensitive breeds or senior dogs with vision concerns

Key features

• Improved Fit & Stability – Secure shape and low profile design reduces movement and increases comfort.
• UV 400 Lenses – Polycarbonate lenses block 99–100% of UVA and UVB rays.
• Increased Field of View – Updated design gives your dog better visibility and awareness.
• Foam Venting System – Prevents fogging and allows for airflow.
• Interchangeable, Scratch-Resistant Lenses – Each pair includes a clear lens and a smoke lens.
• Adjustable Straps – Customizable fit ensures goggles stay put, even during active movement.
• Durable & Lightweight – Built to withstand hard use while remaining comfortable for long wear.

Built for the trail. Trusted in the field.

Rocky Mountain Dog is proud to be an official and exclusive Canadian partner of Rex Specs (aka the industry leader in canine eye protection). These are the same goggles used by working dogs, search-and-rescue teams, military K9s, and active dogs around the world.

Fit & Sizing

1. Head Circumference

Measure the head circumference where you expect the goggle to land on the forehead - typically an inch or so behind the eyes.

2. Muzzle Circumference

Measure the circumference of your dog’s muzzle where you expect the goggle to land on their nose - usually around the back of their mouth.

*Small-Wide designed for dogs with a wide, flat face i.e. Boston Terriers

Note: If your dog is in between sizes select the larger size. This will ensure the most functional fit and optimal field of view.

Pro tip

When properly fitted, your dog’s eyes should sit closer to the middle of the goggle lens, not the bottom. This ensures the best coverage, comfort, and field of vision. If the eyes sit too low, the goggles may not be the correct size.

Your dog might need a few short sessions to adjust. Start slow, use rewards, and let them build confidence. Before you know it, the goggles will be part of your regular gear. Remember: prevention is protection. Goggles are cheaper than a vet bill.
