Sunscreen for dogs: Do they need it and how to choose safely

Most dog owners understand the importance of sunscreen for themselves and their children to protect from sunburn and harmful UVA and UVB rays. However, many might not realise that dogs, especially those with certain skin and fur types, also need protection from the sun.

Dogs often spend considerable time outdoors during warmer months, and after heatstroke, sunburn is one of the most common risks for dogs with pale or thin coats. In this guide, we explore why sunscreen is essential for some dogs, which types need it most, and how to choose and apply sunscreen safely.

Understanding Sunscreen and Its Benefits for Dogs

Sunscreen functions by creating a protective barrier on the skin that reduces damage from the sun's harmful ultraviolet rays. It prevents sunburn, which can cause pain, peeling, and in the long term increase the risk of skin cancer.

Sun protection lotions differ from suntan lotions, which are designed to accelerate tanning. For dogs, you want sunscreens that protect and not those that encourage tanning.

Sunscreens are rated by SPF (Sun Protection Factor); a higher SPF means a greater ability to block UV rays and a longer safe sun exposure time. Dogs with fair skin or thin fur require higher SPF protection.

Which Dogs Need Sunscreen?

You may think a dog's fur provides enough protection, but this is not always true. Dogs with dark, dense coats usually have adequate natural protection against sun damage.

However, Weimaraner puppies, for example, and other breeds with light coloured fur, short, fine coats, or areas where the skin is exposed (belly, nose, ears, muzzle) are at more risk from UV damage and should have sunscreen applied to these spots when outdoors.

Additionally, some breeds like the Boxer are more prone to developing skin tumours and cancer, so extra care is warranted to protect their skin from sun exposure.

Choosing the Right Sunscreen for Your Dog

The market now offers sunscreens specifically formulated for dogs, which is the safest option since they are designed to avoid harmful ingredients and suit canine skin.

If you choose a human sunscreen, please ensure it has no zinc oxide or para-aminobenzoic acid (PABA), both of which can be toxic to dogs if licked and ingested. Opt for a fragrance-free, hypoallergenic sunscreen, often those formulated for children, as they contain fewer additives likely to irritate sensitive skin.

• Use a sunscreen with at least SPF 30 to provide effective protection.
• A sunscreen providing broad-spectrum protection against UVA and UVB rays is essential.
• Reapply sunscreen regularly, especially after swimming or heavy panting.
• Never use sunscreen as a substitute for shade or limiting your dog's sun exposure in peak heat.

How to Apply Sunscreen to Your Dog Safely

1. Perform a patch test: Apply a small amount on a limited skin area to check for sensitivity or allergic reactions.
2. Apply 20 minutes before going outdoors: This allows the sunscreen to set and form an effective barrier.
3. Focus on vulnerable areas: These include the nose, ear tips, lips, belly, groin, and other exposed skin.
4. Avoid eyes and mouth: Carefully apply to avoid your dog getting lotion in their eyes or mouth.
5. Reapply frequently: Depending on activity and weather, reapplication every 4-6 hours or after swimming is recommended.

Additional Summer Safety Tips for Dogs

• Provide plenty of fresh water and shade to prevent overheating.
• Avoid walking dogs during the hottest parts of the day.
• Never leave dogs in parked cars during warm weather.
• Keep an eye on signs of discomfort or sunburn such as redness, peeling, or licking of certain areas.

Summary

Protecting your dog from sun damage is an important part of responsible pet ownership, especially for breeds prone to sunburn and skin cancer. Choosing the right sunscreen product, applying it properly, and combining sun protection with shade and hydration keeps your dog safe and comfortable during sunny days.
