Is Your Pet at Risk? How Climate Change Affects Dogs & Cats

Climate Change and Pet Health: A Silent Threat

Climate change is not just a danger for humans. Rising temperatures and ecosystem changes are causing an increase in diseases that also affect our companion animals. Dogs and cats are increasingly exposed to parasites, viruses, and bacteria that were not previously present in many areas.

Why Climate Change Can Affect Your Pet?

Which Climate-Transmitted Diseases Affect Pets?

Zoonotic and vector-borne diseases (such as those transmitted by mosquitoes and ticks) are on the rise due to global warming. Some of the most common include:

Leishmaniasis

Transmitted by the sandfly (a type of mosquito), it can cause skin problems, weight loss, and in severe cases, kidney failure in dogs.

Heartworm Disease (Dirofilariasis)

Transmitted by mosquitoes, this disease affects the heart and lungs, causing respiratory failure and heart failure if not treated in time.

Symptoms to Watch for in Your Pet

Detecting symptoms of climate-related diseases early can make a big difference in your pet’s health. Some insect-borne infections, such as leishmaniasis or heartworm disease, progress silently and their effects can be serious if not treated soon enough.

Common Signs in Dogs and Cats

• Unexplained weight loss: Even while eating normally, your pet may lose weight.
• Lethargy or excessive tiredness: If they sleep more than usual or don’t want to play or go for walks.
• Persistent cough: Especially in cases of heartworm, a chronic dry cough can appear.
• Skin problems: Wounds that don’t heal, localized hair loss, or skin inflammation.
• Nosebleeds: Can be a sign of advanced leishmaniasis.
• Difficulty breathing: Indicates cardiopulmonary problems that need immediate attention.
• Fever or swollen lymph nodes: Signs that the immune system is responding to an infection.

What to Do If You Notice These Symptoms?

Don’t wait for the situation to worsen. Visit your veterinarian as soon as possible to perform diagnostic tests and, if necessary, start antiparasitic or pharmacological treatment. Early diagnosis can prevent major complications and improve your pet’s quality of life.

Prevention Measures to Protect Your Pet

The best way to protect your pet from climate change is through prevention and regular veterinary care. We recommend:

• Early diagnosis: Perform periodic tests to detect insect-transmitted diseases.
• Vaccination and antiparasitics: Apply products recommended by professionals and follow the vaccination schedule.
• Regular veterinary visits: Allow for health monitoring and prevention of complications.
• Avoid walks during peak exposure hours: Such as dawn and dusk, when mosquito activity is highest.

Awareness Campaigns on Animal Health and Climate

Organizations like Medivet and veterinary clinics are launching educational campaigns about the effects of climate change on pets. These campaigns include preventive services, free information, and discounts on antiparasitic treatments.
