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

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.
