Keeping up with vaccines, parasite prevention, and heartworm testing can feel overwhelming when you are juggling work, family, and a busy Houston schedule. Many pet parents know they should stay on top of preventive care but find it hard to carve out time or budget for a traditional veterinary visit.
That is where CityVAX comes in. CityVAX brings low-cost, high-quality preventive veterinary care directly into Houston-area neighborhoods through convenient walk-in pop-up clinics. Hosted at familiar places like pet resorts, community centers, and local businesses, our clinics make it simple to keep your dog or cat protected without appointments, long drives, or surprise costs.
From core vaccinations to parasite prevention and heartworm testing, CityVAX focuses on the preventive services that keep pets healthier and safer over the long term. For anything outside that scope, we connect you with full-service veterinary clinics that can provide more advanced care.
Heartworm disease is a serious, potentially fatal condition spread by mosquitoes, and it is a year-round concern in the Houston area. Because heartworms live in the heart and lungs, treatment is lengthy, expensive, and risky. The simplest way to protect your pet is regular testing and consistent prevention.
Heartworm testing is a quick blood test that checks for signs of heartworm infection. At a CityVAX pop-up clinic, a team member will gently draw a small blood sample from your dog, then run a rapid test that looks for heartworm proteins in the bloodstream. Results are typically available during your visit, so you know where your pet stands before you leave.
Dogs should be tested regularly, especially before starting or restarting heartworm prevention. In many cases, annual testing is recommended so that any infection can be caught as early as possible. Early detection gives you and your full-service veterinarian more options and a better chance at successful treatment.
Houston’s warm, humid climate creates an ideal environment for mosquitoes. That means local dogs and outdoor cats are at higher risk for exposure to heartworm disease. Even indoor pets can be bitten by mosquitoes that come in through open doors or windows.
Because early heartworm infections may not cause obvious symptoms, you cannot rely on how your pet looks or acts. A dog can appear healthy while heartworms are quietly damaging the heart and lungs. Regular heartworm testing is the only way to know whether your pet is truly protected.
Without testing, starting heartworm prevention on an already infected dog can be unsafe. That is why a heartworm test is so important before beginning or restarting preventive medication, especially if there has been any gap in coverage.
CityVAX clinics are designed to be quick and straightforward for both you and your pet. When you arrive, you will check in with our team, share any previous records you have, and let us know you are interested in heartworm testing. Because our clinics are walk-in only, you do not need to schedule ahead or commit to a specific time.
After the blood sample is collected, we will run the test on-site. Once results are available, our team will review them with you, answer questions about your pet’s risk, and discuss appropriate next steps for prevention. If your pet needs further evaluation or treatment for any reason, we will direct you to a full-service veterinary clinic that can provide that level of care.
Most pet parents find it easiest to bundle heartworm testing with other preventive care during the same visit. At CityVAX, you can take advantage of:
Low-cost pet vaccinations for dogs and cats, including core vaccines such as:
We also offer flea, tick, and parasite prevention products to help guard against itchy infestations and intestinal parasites, as well as microchipping to improve your chances of being reunited with a lost pet.

Because we focus on preventive services only, visits tend to be faster and more efficient. You are there for vaccines, parasite prevention, heartworm testing, or microchipping, and our team is set up specifically for those needs. That focused scope helps keep costs down and wait times shorter.

If you have never visited a CityVAX pop-up before, you might be wondering what the process looks like. Our clinics are designed for simplicity and transparency. When you arrive during the posted event time, you will check in, share any previous records you have, and let us know which preventive services you are interested in, such as heartworm testing, vaccinations, parasite prevention, or microchipping.
Our team will walk you through recommended services based on your pet’s age, species, and lifestyle, then provide those services during the same visit. Before you leave, you will receive documentation of the vaccines and treatments your pet received so you can keep your records up to date or share them with your regular veterinary clinic.
For any issues outside the scope of preventive care, such as illness, injury, or more advanced diagnostics, we will refer you to a full-service veterinary clinic that can provide a complete medical workup and treatment plan.
