You know your dog or cat needs regular preventive care, but fitting full-service vet visits into a busy schedule and tight budget can be tough. Between work, family, traffic, and rising costs, it is easy to put off routine services like vaccines, parasite prevention, and heartworm testing.
CityVAX was created for exactly that gap. Our walk-in pop-up clinics bring affordable, high-quality preventive veterinary care to familiar spots around the greater Houston area, including Pearland, League City, Richmond, and Texas City. You stop by while you are already out running errands or heading to the gym, get your pet what they need, and get back to your day.
This week, we are highlighting one of the most important services we offer: low-cost heartworm testing. If you live in Southeast Texas, this simple test is one of the most powerful tools you have to protect your pet’s health.
Heartworm disease is spread by mosquitoes, which thrive in our warm, humid Gulf Coast climate. That means dogs and, less commonly, cats in the Houston area are at risk year-round. Once heartworms mature in a pet’s heart and lungs, treatment is lengthy, expensive, and can be risky for the animal.
Regular heartworm testing and consistent prevention give you a much better alternative. Testing lets you catch an infection early or confirm that your pet is heartworm-free before starting or continuing prevention. Early prevention is safer and far less expensive than treatment after disease has developed.
At a CityVAX pop-up clinic, heartworm testing is designed to be quick, gentle, and efficient. Here is what you can expect:
For dogs:
For cats: Your CityVAX team member will discuss whether testing is appropriate based on your cat’s lifestyle and risk, then guide you on next steps and prevention options. Heartworm disease looks different in cats than in dogs, so the approach can vary.
The blood draw is brief and handled by trained veterinary professionals who focus on keeping your pet as calm and comfortable as possible.
In our region, many pets benefit from annual heartworm testing, especially dogs. Testing is particularly important if:
The CityVAX team can help you understand your pet’s risk factors and recommend an appropriate testing schedule, then connect you with a full-service veterinary clinic if further diagnostics or treatment are needed.
Heartworm testing is just one part of a strong preventive care plan. At our pop-up clinics, you can pair testing with other essential services, such as:
For any health concerns outside of preventive care, such as illness, injury, or chronic conditions, CityVAX will refer you to a trusted full-service veterinary clinic. Our role is to make the routine, high-impact preventive care as easy and accessible as possible.
CityVAX clinics are built around convenience and accessibility. They are walk-in only, so there is no need to find a time that works for both you and a traditional veterinary hospital. You simply check our schedule, pick a nearby location, and stop by during the posted hours.
Because we focus on preventive care, visits are typically faster and more streamlined than a full-service appointment. You get clear, focused guidance on vaccines, parasite prevention, heartworm testing, and microchipping, without the added time or cost of services your pet may not need that day.
Our pop-up clinics are hosted at community locations you already know, such as PetSuites, Pet Evolution, Advance Auto Parts, and local YMCA branches. Many pets feel more relaxed in these everyday environments compared to a traditional clinic lobby. That can mean less stress for them and less stress for you.
CityVAX is on the move across the Houston area. All clinics listed below are walk-in only. No appointment needed — just come during the time window that works best for you.

If you are not sure when your pet last had a heartworm test or if they are behind on vaccines and parasite prevention, this is an easy time to get caught up. Stop by the CityVAX pop-up that is most convenient for you, bring any previous vaccination or medical records you have, and our team will guide you through the preventive services that make sense for your pet.
You can explore all of our preventive offerings on the CityVAX services page, or check for additional dates and locations on our regularly updated schedule and locations page. If you have questions before you come, call (832) 281-0559 and a CityVAX team member will be happy to help. For any needs beyond vaccines, parasite prevention, heartworm testing, and microchipping, we will refer you to a full-service veterinary clinic that can provide complete medical care.
