Heartworm & Tick Fever Testing

What Is Heartworm Disease in Pets and Why Is It a Concern in Phoenix?

Heartworm disease is caused by parasitic worms (Dirofilaria immitis) that are transmitted through the bite of an infected mosquito. Once inside the body, the immature worms travel through the bloodstream to the heart and lungs, where they grow into adults. These worms can damage the heart, lungs, and surrounding blood vessels, leading to severe health complications.

In Phoenix, mild winters allow mosquito populations to survive year-round. This means pets here face constant exposure to the parasite, even in months when owners might think the risk is low. Because heartworm disease often develops silently, many pets do not show symptoms until the damage is advanced. By then, treatment is more complicated, costly, and risky, which is why prevention and regular testing are so important.

How Often Should My Pet Be Tested for Heartworm?

Veterinary guidelines recommend annual heartworm testing for both dogs and cats. Even if your pet is on a year-round prevention program, testing once a year ensures the medication is working and catches any infections early.

For pets that have missed doses, were adopted without a clear medical history, or have been exposed to mosquitoes during travel, testing may be recommended more frequently. At SNiP Vet, we can advise you on the right testing schedule based on your pet’s lifestyle and risk factors.

Why Is Year-Round Heartworm Prevention Important in Phoenix?

In some parts of the country, owners can stop prevention during colder months, but in Phoenix, mosquitoes are a year-round reality. Even a single missed dose of preventive medication can leave your pet unprotected and at risk of infection.

Year-round prevention not only guards against heartworms but also helps protect against other parasites, depending on the product chosen. Our team will recommend the most effective preventive options for your pet, taking into account their age, size, and daily activities.

How Is Heartworm Testing Done at a Veterinary Clinic?

At SNiP Vet, our canine heartworm test and feline heartworm test are quick, minimally invasive, and performed right here in our Phoenix veterinary clinic. We draw a small blood sample from your pet, then use an antigen test to detect proteins released by adult female heartworms.

The process usually takes just a few minutes, and results are available during your visit. If the test is negative, your pet can continue or start preventive medication immediately. If it’s positive, we will help you find a full-service veterinary hospital to begin treatment.

What Is Tick Fever and How Is It Spread in Phoenix?

Tick fever, also called Ehrlichiosis, is a bacterial infection transmitted by the brown dog tick, which is especially common in Arizona. Once a tick carrying Ehrlichia bacteria bites a dog, the bacteria enter the bloodstream and begin attacking the white blood cells, impacting the immune system.  Tick fever can also cause issues with blood clotting, which can lead to more complications during routine surgeries such as spays and neuters.  Despite its name, tick fever often does not show any outward signs or symptoms like a fever and can be hiding in dogs who appear to be completely healthy.

Because Phoenix’s climate supports tick survival throughout the year, pets can be exposed during any season. Unlike heartworms, which are spread by mosquitoes, tick fever spreads directly through tick bites, making flea and tick prevention equally important.

What Are the Early Signs of Heartworm Disease and Tick Fever in Pets?

Heartworm Disease Symptoms:

• Persistent cough
• Fatigue after mild exercise
• Decreased appetite
• Weight loss
• Swollen belly from fluid buildup in advanced cases

Tick Fever Symptoms:

• Fever
• Lethargy or depression
• Loss of appetite
• Enlarged lymph nodes
• Abnormal bleeding, nosebleeds, or bruising

It’s important to note that many pets show no symptoms in the early stages, which is why annual testing is critical.

Can My Pet Be Tested for Both Heartworm and Tick Fever at the Same Time?

Yes, at SNiP Vet, we offer combined testing for heartworm and tick fever during the same visit. This efficient approach reduces stress for your pet, saves you time, and ensures that two of the most serious vector-borne diseases in Arizona are screened for at once.

How Can I Prevent Heartworm and Tick Fever in My Pet?

Effective prevention includes:

• Monthly heartworm preventive medication year-round
• Flea and tick control products to prevent bites and disease transmission
• Regular checkups and parasite screening to monitor your pet’s health

Our veterinary team can recommend safe, effective products tailored to your pet’s needs, and show you how to administer them properly for maximum protection.
