How to Protect Your Dog From the Sun

Just like people, dogs are susceptible to sunburn, heat exhaustion, and dehydration. With a little preparation, you can keep your dog safe and comfortable all summer long.

Preventing Sunburn in Dogs

Fur doesn't fully protect against UV rays. Dogs with thin hair, no hair, or light-colored skin are especially vulnerable to sunburn — which can cause pain, skin damage, and fur loss. Keep your dog out of direct sun during peak hours (10am–4pm), and use pet-safe sunscreen when shade isn't available.

Choosing Dog Sunscreen

Never use human sunscreen on dogs — zinc oxide is toxic when ingested. Look for a pet-specific sunscreen that blocks both UVA and UVB rays with SPF 15 or higher. Choose waterproof if your dog swims, and fragrance-free for sensitive skin.

Applying Dog Sunscreen

Test on a small skin area first and monitor for irritation. If no reaction occurs, apply to exposed areas: face, abdomen, legs, and ear tips. Avoid eyes and minimize inhalation with spray formulas. Allow it to soak in, then distract your dog with a treat to prevent licking. Reapply every 2–3 hours, or more often after swimming. Browse our dog treat collection for distraction treats.

Sun-Protective Clothing

Lightweight sun shirts, bodysuits, hats, and dog goggles can provide additional protection for sun-sensitive dogs. Look for breathable fabrics to keep them cool.

Preventing Heatstroke in Dogs

Dogs cool themselves primarily through panting — they don't sweat like humans. When panting isn't enough, body temperature rises rapidly and heatstroke can follow.

Signs of Heat Exhaustion

• Excessive panting and salivation
• Lethargy or weakness
• Bright or dark red tongue and gums
• Rapid heart rate
• Thick or sticky saliva
• Vomiting, collapsing, seizures, or loss of consciousness (severe)

What to Do if Your Dog Overheats

Move them to a cool environment immediately, then:

• Place them in a cool (not cold) bath or shower
• Apply a cold pack to the back of their neck
• Massage their legs to improve circulation and prevent shock
• Ensure they drink plenty of water

What to Do in a Heatstroke Emergency

Heatstroke is a medical emergency. Remove your dog from the heat and get to a vet immediately. While transporting:

• Place cool, wet cloths on their head, neck, abdomen, groin, and feet — do not use ice water
• Direct a fan or AC toward their body

More Tips to Prevent Overheating

• Never leave your dog in a car. Temperatures can reach 90°F in just 10 minutes on a 70°F day — cracking windows makes little difference.
• Don't over-exercise in the heat. Walk and play in the morning or evening. See our guide on walking your dog safely in summer.
• Avoid hot surfaces. Concrete, asphalt, and sand can burn paw pads and radiate heat. Stick to grass when possible.
• Don't muzzle in the heat. Muzzles prevent panting, which is your dog's primary cooling mechanism.
