Quick answer

Our top pick is Epi-Pet Sun Protector Spray for Dogs. It is specifically formulated for dogs, SPF 30+, and easy to apply on small dogs. For a budget-friendly option, try Burt’s Bees Dog Sunscreen Spray. If your dog has sensitive skin, consider the Natural Dog Company Sun Stick.

What to consider for Dog Sunscreen For Dogs Under 20 Lbs

Small dogs have thinner skin and less fur coverage, making them more susceptible to sunburn. Look for sunscreens with safe ingredients like zinc oxide (non-nano) or titanium dioxide, and avoid those with fragrances or alcohol. Choose a water-resistant formula if your dog swims or plays in water. Consider the application method: sprays are quick for full-body coverage, while sticks are good for targeted areas like the nose and ears. Always test a small area first for allergic reactions.

What to look for in a grooming product (shampoo, brush, clipper or wipe)

For a sunscreen, look for a product specifically labeled for dogs, as human sunscreens can contain toxic ingredients like zinc oxide nanoparticles or oxybenzone. The sunscreen should be fragrance-free and hypoallergenic to minimize irritation. Easy application is key for small, wiggly dogs; sprays or wipes are convenient. A non-greasy formula helps avoid staining furniture. Also, check the SPF rating; at least SPF 15 is recommended, but SPF 30+ provides better protection.

Why this matters

Small dogs under 20 pounds have a higher surface-area-to-volume ratio, making them more susceptible to sunburn and heat-related issues, so consistent sunscreen use is crucial.

The Options

Types Explained

Spray Sunscreen

A liquid spray that can be applied quickly over large areas. Ideal for full-body coverage on small dogs with short hair.

Best for: Dogs that tolerate spray and need quick application.

Sun Stick

A solid stick that glides on easily for targeted application. Great for noses, ears, and other sensitive spots.

Best for: Dogs with sensitive skin or for precise application.

Sunscreen Wipes

Pre-moistened wipes that allow for controlled application without mess. Good for dogs that dislike sprays.

Key Buying Factors

SPF Level

Choose at least SPF 15, but SPF 30 or higher is better for extended outdoor time. Higher SPF blocks more UVB rays, reducing sunburn risk.

Ingredients

Look for dog-safe ingredients like non-nano zinc oxide or titanium dioxide. Avoid oxybenzone, octinoxate, and fragrances that can irritate or be toxic.

Application Method

Sprays are quick for full-body coverage, sticks are precise for sensitive areas, and wipes are mess-free. Consider your dog's tolerance for each method.

Water Resistance

If your dog swims or gets wet, choose a water-resistant formula. Check the label for duration (e.g., 80 minutes) and reapply as needed.

Size and Portability

For small dogs, a compact bottle or stick is convenient for travel. Ensure the product is easy to carry on walks or trips.

Living With It

Care, Cost and Maintenance

How to Apply Sunscreen

Apply sunscreen 15 minutes before sun exposure. For sprays, hold 4-6 inches away and spray evenly, avoiding eyes and mouth. For sticks, glide over nose, ears, and belly. Reapply every 2 hours or after swimming.

How Often to Reapply

Reapply sunscreen every 2 hours, or more often if your dog is swimming or sweating. Check the product label for specific water resistance duration. Do not rely on a single application for all-day protection.

Sun Safety Tips

Limit sun exposure during peak hours (10 AM to 4 PM). Provide shade and fresh water. Use dog-safe sunscreen on exposed skin, especially on light-colored or thin-coated dogs. Consider protective clothing for extra coverage.

Pro tip

For best protection, apply sunscreen to your dog's belly and inner thighs, as these areas are often overlooked but highly exposed when your dog lies down.

Frequently asked questions

How often should I apply sunscreen to my small dog?

Apply sunscreen 15 minutes before going outside, and reapply every 2 hours. If your dog swims or gets wet, reapply immediately after drying. For dogs with very short or light-colored fur, more frequent application may be needed. Always follow the product's instructions for best results.

Can I use human sunscreen on my dog?

No, human sunscreen often contains ingredients like oxybenzone or zinc oxide nanoparticles that can be toxic if ingested. Dogs lick their skin, so it's important to use a dog-specific sunscreen with safe ingredients. Look for products with non-nano zinc oxide or titanium dioxide and avoid fragrances.

What SPF is recommended for dogs?

At least SPF 15 is recommended, but SPF 30 or higher provides better protection. Small dogs with thin coats or light skin are more prone to sunburn, so a higher SPF is advisable. Remember that SPF measures UVB protection; look for broad-spectrum products that also block UVA rays.

How do I apply sunscreen to a wiggly small dog?

Use a product with an easy application method like a spray or wipe. Distract your dog with treats or have a helper hold them gently. Apply quickly, focusing on exposed areas like the nose, ears, and belly. Practice during calm moments to make it a positive experience.

Is sunscreen safe for dogs with sensitive skin?

Yes, but choose a fragrance-free, hypoallergenic formula with natural ingredients like aloe vera or coconut oil. Test a small patch first to check for reactions. Avoid products with alcohol or essential oils that can irritate. If redness or itching occurs, discontinue use and consult your veterinarian.

Can I use sunscreen on my dog's nose?

Yes, the nose is a common area for sunburn, especially on light-colored dogs. Use a sun stick or balm specifically designed for dogs, as it is safe if licked. Apply a thin layer and reapply after your dog drinks or eats. Avoid getting it in the nostrils.

What ingredients should I avoid in dog sunscreen?

Avoid oxybenzone, octinoxate, homosalate, and octocrylene, which can be toxic or irritating. Also avoid zinc oxide nanoparticles (non-nano is safe) and fragrances. Stick to dog-safe brands that list ingredients transparently. When in doubt, consult your vet.

Do all dogs need sunscreen?

Dogs with thin or white fur, light skin, or hairless breeds are at higher risk. However, any dog can get sunburned, especially on the nose, ears, and belly. If your dog spends time outdoors, especially during peak sun hours, sunscreen is a good precaution. Consult your vet for personalized advice.

Can sunscreen expire?

Yes, sunscreen can expire and lose effectiveness. Check the expiration date on the bottle. Most sunscreens are good for about 2 to 3 years. If the texture, color, or smell changes, discard it. Store sunscreen in a cool, dry place to maintain its potency.

A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
