Sun-Induced Skin Cancer in Pets: Protecting Your Dog or Cat with Pet-Safe Sunscreen

At TLC Animal Hospital in El Paso, TX, we know how much our pets love soaking up the sun. But just like people, dogs and cats can be at risk for sun-induced skin cancer. Pets with light-colored fur, thin coats, or exposed skin are especially vulnerable. Fortunately, there are preventive measures you can take—including the use of zinc-free, pet-safe sunscreen. Read on to learn how to protect your furry friend from harmful UV rays.

Understanding Sun-Induced Skin Cancer in Pets

Sun-induced skin cancer occurs when prolonged exposure to ultraviolet (UV) rays damages the skin’s DNA, leading to abnormal cell growth. In dogs and cats, the most common types include:
- **Squamous cell carcinoma**
- **Hemangioma and hemangiosarcoma**
- **Basal cell carcinoma**

These cancers most often develop on areas with little to no fur coverage, such as the nose, ears, belly, and eyelids.  

Pets Most at Risk

Certain pets are more susceptible to sun-related skin issues:
- Light-colored or hairless breeds (e.g., Dalmatians, White Boxers, Sphynx cats, white colored cats)

- Certain dog breeds such as Pit Bulls and Greyhounds
- Pets with thin coats or shaved areas
- Pets who love sunbathing (including in the window) or spend extended time outdoors
- Animals with previous sunburns or skin trauma

Signs of Sun Damage and Skin Cancer

Be on the lookout for these signs:
- Red, inflamed, or scaly patches of skin
- Ulcers or sores that don’t heal
- Bleeding or crusting skin
- Lumps or raised lesions

- Flat or raised red to purple skin lesions
- Hair loss in affected areas

If you notice any of these signs, consult a veterinarian promptly for evaluation. If caught early, these cancers may be controlled with minimally invasive techniques, such as surgical laser ablation.  Large or more extensive tumors may require surgical removal and biopsy.

The Role of Pet-Safe Sunscreen

Sunscreen can be an effective preventive tool when used correctly. However, not all sunscreens are safe for pets—many contain zinc oxide, which is toxic if ingested (i.e. from licking during normal self-grooming).

Look for sunscreens that do not have any zinc oxide in the ingredients list.  Pet-safe or children’s sunscreens are usually good options (still check the ingredient label for zinc). Avoid contact with the eyes.  Apply creams to the ears and nose.  Sprays can be used for the rest of the body. Apply before your pet heads outside and reapply as directed, especially after swimming or prolonged sun exposure.

Additional Sun Safety Tips

- Limit outdoor time during peak UV hours (10 a.m. to 4 p.m.).
- Provide access to shade at all times.
- Use protective clothing like UV-blocking shirts or hats for sensitive pets.
- Avoid shaving your pet’s coat too short—fur provides natural sun protection.
