Houston’s mild winters may seem like a break from the pests and problems of warmer seasons, but for local pet owners, February is actually a critical time to think about heartworm protection. If you have ever wondered whether your dog or cat really needs heartworm testing this time of year, you are not alone. At CityVAX, our mobile, low-cost pet vaccination clinic brings convenient, affordable care directly to Houston and surrounding communities. We understand that you want to protect your pets without stress or hassle, and that is why our caring veterinary team offers walk-in pop-up events with no appointment needed—making it easy to keep your pets healthy right when it matters most.
In this blog, we will explore why heartworm testing is so important for Houston pets in February, how heartworm disease develops, what signs to watch for, and how CityVAX can help you stay ahead of this silent threat. We will also walk you through what to expect at a mobile event, give practical prevention tips, and explain when to seek veterinary care. If you are curious about affordable, accessible heartworm testing options in Houston, you are in the right place.
Living in Houston means enjoying warmer temperatures, even in February. While many regions see a drop in mosquito activity during winter, our local climate keeps mosquitoes buzzing nearly all year long. Because mosquitoes are the primary carriers of heartworm larvae, this means that the risk of heartworm infection never truly disappears for Houston pets.
Owners may occasionally notice their dogs or cats scratching more, becoming lethargic, or developing a lingering cough. These subtle symptoms can sometimes be early hints of heartworm infection, but the tricky part is that heartworm disease often progresses for months without any obvious signs. By the time you see more serious symptoms—such as difficulty breathing, exercise intolerance, or weight loss—the disease may already be advanced.
February is a key time to test because the risk is ongoing, yet owners may assume that cooler weather means there is no need for vigilance. In reality, skipping heartworm testing can leave your pet exposed just as mosquito populations start to rise again with spring approaching. With CityVAX’s mobile events right in your neighborhood, staying ahead of heartworm is easier than ever.
Heartworm disease begins with a single mosquito bite. When an infected mosquito bites your pet, it can deposit microscopic heartworm larvae into the bloodstream. Over several months, these larvae mature into adult worms that settle in the heart, lungs, and blood vessels. Dogs are the natural host for heartworms, so they are especially vulnerable, but cats can be infected as well—often with even more severe consequences.
Houston’s climate, with its humidity and mild winters, creates ideal breeding conditions for mosquitoes. This is why heartworm is a persistent issue in the area, not just a seasonal threat. Many owners mistakenly believe indoor pets are safe, but mosquitoes easily find their way indoors, putting even strictly indoor dogs and cats at risk.
Without regular heartworm testing, an infection can go undetected for a long time. By the time heartworm disease is apparent, it often requires far more complex and expensive treatment, and in some cases, the damage may be irreversible. Early detection is the best way to ensure a simple, affordable solution and a healthy future for your pet.
One of the biggest advantages of choosing CityVAX is the convenience and comfort our mobile veterinary team brings directly to you. At our walk-in, pop-up events, there is no need to schedule an appointment or wrestle a nervous pet into the car for a stressful vet visit. Instead, you and your pet can drop by whenever it fits your schedule, knowing you will receive personalized, compassionate care.
Heartworm testing is a straightforward process. For dogs, a small blood sample is drawn, and the test can typically detect heartworm proteins within just a few minutes. For cats, the testing protocol is slightly different and may involve additional bloodwork, as cats can have very low worm counts that are harder to identify. Our veterinary professionals will explain each step, answer your questions, and make the process as gentle as possible for your pet. Because CityVAX specializes in affordable services, you can keep up with annual testing and protection without breaking the bank.
After testing, our team will discuss the results with you and answer any questions about next steps, whether that means starting heartworm prevention, adjusting your current routine, or guiding you if further care is needed. If your pet is due for other preventive services, such as pet vaccinations, microchipping, or parasite prevention, you can conveniently take care of everything during the same visit.
Preventing heartworm disease is much easier and safer than treating it. The foundation of prevention is regular use of veterinarian-recommended heartworm preventives, which come in forms such as monthly chewable tablets, topical solutions, or injections. Your pet’s lifestyle, age, and health status will determine which product is best, and our CityVAX veterinary team is happy to help you choose the right protection.
In Houston’s climate, year-round prevention is essential. Stopping medication during cooler months can leave a window for infection, as mosquitoes remain active even in February. Along with preventive medication, annual heartworm testing is crucial because no preventive is 100 percent effective, and early detection can catch infections before they cause lasting harm.
Home care steps also include keeping your environment as mosquito-free as possible. This means eliminating standing water where mosquitoes breed, using screens on windows and doors, and bringing pets indoors during peak mosquito activity at dawn and dusk. While these steps help, they cannot replace the need for reliable veterinary prevention and regular testing.
If you notice any changes in your pet’s health, such as persistent coughing, shortness of breath, reduced energy, or loss of appetite, it is important to seek veterinary attention promptly. These can be signs of heartworm disease or other serious conditions. Because heartworm often goes undetected in its early stages, even healthy-appearing pets need regular screening.
CityVAX makes it simple to get your pet tested and protected. With our walk-in, mobile events throughout Houston and surrounding neighborhoods, you do not need to wait or worry about scheduling—just stop by when it is convenient. Our veterinary professionals are trained to recognize and discuss any concerns you may have, and if your pet tests positive for heartworm, we will guide you on the next steps, including referrals for further treatment if needed.

For routine testing, prevention, and peace of mind, CityVAX is your trusted neighborhood resource.
February marks the transition from winter to spring in Houston, and with it comes a rise in mosquito activity.
