Your dog loves the backyard, the dog park, and every trail you explore together. Your cat may only venture onto the patio, but mosquitoes and hitchhiking fleas do not care where your pet spends their time. Parasites are a year-round reality in the Houston area, and protecting your pet can feel overwhelming and expensive.
Between busy schedules, traffic, and the cost of traditional vet visits, many pet parents put off preventive care longer than they would like. That is exactly where CityVAX comes in. Our walk-in pop-up vaccination clinics bring affordable, high-quality preventive care right into Houston-area neighborhoods, so you can protect your pet on your terms.
CityVAX partners with trusted community venues across Pearland, League City, Richmond, and beyond to offer low-cost vaccinations, parasite prevention, heartworm testing, and microchipping. No appointment, no exam fee, and no complicated scheduling. Just caring veterinary professionals focused on keeping your pet healthy and protected.
Houston’s warm, humid climate is paradise for parasites. Fleas, ticks, and mosquitoes thrive here, which means dogs and cats are at risk even if they spend most of their time indoors. CityVAX makes it easier and more affordable to stay ahead of these threats with veterinarian-recommended prevention products available at our pop-up clinics.
Fleas are more than an itchy nuisance. They can trigger allergies, cause skin infections, and lead to serious anemia in small or young pets. They can also carry tapeworms and other diseases. Once fleas infest your home, they are notoriously hard to get rid of.
At CityVAX pop-up clinics, our team can help you choose effective flea prevention tailored to your dog or cat’s size, lifestyle, and health history. We offer preventive products that:
We can also answer common questions such as how often to give prevention, what to do if you miss a dose, and how to manage a household flea problem while keeping your pet safe.
Ticks are less obvious than fleas but can be even more dangerous. They can transmit serious illnesses to pets, and many pets do not show signs of tick bites right away. In our region, ticks can be active during much of the year, especially in grassy, wooded, or brushy areas.
CityVAX pop-up clinics carry tick prevention options for dogs and cats that are designed to:
Our team can show you how to check your pet for ticks, what to watch for after a tick bite, and how to choose a product that fits your pet’s outdoor routine. If we are concerned about anything outside the scope of preventive care, we will recommend follow-up with a full-service veterinary clinic.
Heartworm disease is a major concern in the Houston area because mosquitoes are active for much of the year. Mosquitoes can carry heartworm larvae that mature into long worms living in a pet’s heart and lungs. Untreated heartworm disease can be life-threatening and treatment can be lengthy and costly for dogs. For cats, there is no approved treatment, so prevention is especially important.
At CityVAX, we focus on making heartworm prevention both accessible and understandable. Our pop-up clinics offer:
We follow current veterinary guidelines that recommend annual heartworm testing for dogs, even when they are on prevention. This helps catch any lapses or rare product failures early. If a test ever comes back positive, we will explain the next steps and refer you to a full-service veterinary clinic for further evaluation and treatment planning.
Flea, tick, and heartworm prevention works best when it is part of a consistent, long-term plan. CityVAX pop-up clinics are designed to support that plan by offering:
If your pet has medical conditions, is pregnant, or is on other medications, our team will help you understand which options may be appropriate and when to consult a full-service veterinarian for personalized care.

CityVAX pop-up clinics are built around the way people in the Houston area actually live. Long workdays, family commitments, and traffic can make it difficult to get to a traditional veterinary clinic for quick preventive care. Our model focuses on convenience and affordability without sacrificing quality.
All CityVAX clinics are walk-in. You simply arrive during the posted time window, check in, and our team will guide you through services such as vaccinations, parasite prevention, heartworm testing, and microchipping. Because we focus on preventive care only, visits tend to be more efficient and less stressful for both you and your pet.
Our clinics are hosted at familiar community locations like pet resorts, pet supply stores, YMCAs, and other neighborhood venues. Many pets feel more relaxed in these settings than in a traditional hospital environment. If during your visit we identify a concern that needs more in-depth evaluation, diagnostics, or treatment, we will recommend follow-up at a full-service veterinary clinic.
CityVAX is on the move across the greater Houston area, bringing low-cost parasite prevention and other essential services directly to your side of town. All clinics listed below are walk-in only. No appointment needed.
