If your pet spends any time outside in the Houston heat and humidity, you already know how quickly fleas, ticks, and mosquitoes can show up. Maybe you have meant to stay on top of monthly prevention, but life, budgets, and busy schedules keep getting in the way. Before you know it, you are overdue for refills and wondering where to start.
Preventive veterinary care should be straightforward and affordable, not something you have to rearrange your entire week to manage. That is exactly why CityVAX brings care out into the community. Instead of fitting your life around a clinic’s calendar, our walk-in pop-up clinics fit preventive care into your everyday errands.
CityVAX offers low-cost vaccinations, parasite prevention, heartworm testing, and microchipping at pop-up locations throughout the greater Houston area. No appointment is ever needed. You simply walk in during the clinic window, get the protection your dog or cat needs, and get back to your day.
Fleas, ticks, and heartworms are more than just a nuisance. In the Houston region, our warm climate allows these parasites to stay active almost year-round, which means consistent prevention is essential for both dogs and cats.
Fleas can cause intense itching, allergic reactions, skin infections, and even anemia in severe infestations. They also spread tapeworms. Once fleas are in your home, they can be difficult and expensive to eliminate. That is why monthly prevention is far easier than battling an infestation later.
At CityVAX pop-up clinics, our team can help you choose affordable flea prevention that fits your pet’s size, species, and lifestyle. We focus on:
Indoor pets are not automatically safe from fleas. Fleas can hitch a ride in on shoes, clothing, or visiting pets. Consistent prevention keeps your pet comfortable and protects your home environment.
Ticks are less obvious than fleas but can cause more serious disease. They can transmit conditions that lead to fever, joint pain, and long-term health problems. In wooded areas, dog parks, and even neighborhood green spaces, ticks can be waiting in the grass or brush.
Tick prevention products available at CityVAX pop-ups are designed to kill or repel ticks before they can attach long enough to spread disease. When you visit a clinic, our team will:
If you notice a change in your pet’s behavior or health after a known tick exposure, CityVAX will recommend follow-up with a full-service veterinary clinic for further testing and care.
Heartworm disease is spread by mosquitoes and is very common in Texas. Mosquitoes are active for much of the year in the Houston area, which means unprotected pets are at real risk. Heartworms live in the heart and lungs and can cause coughing, exercise intolerance, and heart failure. Treatment is costly and can be risky for dogs. For cats, there is no approved treatment, so prevention is absolutely critical.
CityVAX offers heartworm testing for dogs along with low-cost heartworm prevention options. When you bring your dog to a pop-up clinic, we can:
For cats, our focus is on year-round heartworm prevention because even a few worms can cause serious lung disease. Our team can help you select the right product and explain how to keep protection consistent month after month.
Parasite prevention works best when combined with core vaccinations and microchipping. While you are at a CityVAX event for flea, tick, or heartworm prevention, you can also take care of other preventive needs. Our low-cost pet vaccinations help protect against serious diseases such as rabies, distemper, and parvovirus in dogs, and panleukopenia and respiratory viruses in cats.
If your pet needs care outside of vaccines, parasite prevention, heartworm testing, or microchipping, we will refer you to a full-service veterinary clinic for a complete examination and any additional diagnostics or treatment.
Many pet parents delay preventive care because it feels time-consuming or expensive. CityVAX pop-up clinics are designed to remove those barriers so your pets get the protection they need on a schedule that actually works for you.
Walk-in convenience: No appointment is ever required. Each clinic has a set time window so you can stop by when it fits into your day, whether you are running errands, heading home from work, or already visiting one of our partner venues.
Affordable, focused care: By limiting our services to vaccinations, parasite prevention, heartworm testing, and microchipping, we keep visits efficient and costs lower. This focused model helps more Houston-area pets stay up-to-date on the basics that prevent serious illness.
Community-based and less stressful: CityVAX partners with familiar locations such as PetSuites, pet supply stores, and other neighborhood venues. Many pets are more relaxed in these environments compared to a traditional clinic lobby. Shorter wait times and a simple visit structure are especially helpful for anxious pets and busy families.
CityVAX is proud to serve pets and families across Pearland, League City, Richmond, Katy, Cypress, and surrounding Houston communities. All clinics listed below are walk-in only. No appointment needed — walk-ins welcome!

Bringing your pet to a CityVAX pop-up clinic is simple. Choose the location and time that works best for you, then come by during the posted clinic window. Since everything is walk-in, there is no need to plan weeks ahead or wait for an appointment slot to open.
For the smoothest visit, bring any prior vaccination records you have and a secure leash or carrier for your pet. If you are unsure what your dog or cat needs, our team will help you prioritize core vaccinations, parasite prevention, and heartworm testing based on age, lifestyle, and previous history.
If your pet is sick, injured, or needs care beyond preventive services, we will direct you to a full-service veterinary clinic that can provide a complete examination and treatment plan. CityVAX focuses on keeping healthy pets protected through vaccines, parasite control, heartworm testing, and microchipping so that more Houston-area families can access the basics of preventive care.
