Allow our doctors and well-trained staff to help you select the best and most practical preventatives for you and your pets. Monthly chewies, a 6-month injectable, or flavored tabs for dogs; safe, easy, effective topicals for cats…
We want to keep your pets healthy. You know that an ounce of prevention is worth a pound of cure (thanks, Ben Franklin!). It is way easier (and cheaper) to prevent heartworm disease than to treat it. And it is way less icky to prevent a flea infestation than to find out about it after those boogers have set up shop in your carpet (and rugs and upholstery).
Most of our clients don’t even realize their dogs and cats have fleas until we see their pet in the veterinary clinic.
We have the team to support you, the warranties to rely on, and the prices to help you take the best care of your pets!
Why Heartworm and Flea Prevention Matters in San Antonio
San Antonio's climate is a year-round buffet for parasites. Mild winters mean mosquitoes, fleas, and ticks rarely die off — they slow down at most. That's why heartworm and flea prevention isn't a seasonal concern in South Texas. It's a 12-month commitment.
Heartworm disease is transmitted by a single mosquito bite. Once infected, a pet develops worms that grow up to a foot long inside the heart and pulmonary arteries. The disease is silent until it's advanced — and by the time symptoms appear (coughing, exercise intolerance, weight loss), significant damage has already been done. Texas consistently ranks among the top states in the country for heartworm prevalence. Prevention is dramatically less expensive — and dramatically less risky — than treatment.
Fleas are more than an itch. A single flea can lay 50 eggs a day, and an established flea problem in your home can take months to fully resolve. Fleas also carry tapeworms and bartonella ("cat scratch disease"), and some pets develop flea allergy dermatitis — a severe allergic reaction to a single flea bite that turns into chronic skin infections.
Ticks transmit Lyme disease, ehrlichiosis, anaplasmosis, and Rocky Mountain spotted fever — several of which are present in Texas.
The good news: modern parasite prevention is highly effective, well-tolerated, and easy to give. Monthly chewables, topicals, and longer-acting injectable options make it easy to find a product that fits your pet and your routine. Annual heartworm testing catches the rare prevention failure early and is required to renew most prescriptions.
FAQs for Heartworm & Flea Prevention
Yes. Mosquitoes are active essentially year-round in South Texas, and even short gaps in prevention create risk. Year-round prevention is the standard of care.
