Heartworm and Parasite Prevention in Tampa: A Year-Round Guide

Parasite prevention is a year-round job in Tampa, not a summer chore. Our mild winters let mosquitoes, fleas, and ticks stay active all 12 months. That means the threat to your dog or cat never really pauses. At Gregory Veterinary Clinic in Carrollwood, we treat the results of missed prevention every week, and almost all of it is avoidable. Here is what real protection looks like.
Why Florida pets need year-round protection
Cold winters kill off parasites in northern states. Tampa never gets that reset. Mosquitoes, fleas, and ticks keep breeding here through December and January. A summer-only plan leaves a wide gap the rest of the year. The AVMA recommends year-round prevention for exactly this reason. One missed month can be enough for an infection to take hold.
Heartworm: the most dangerous, and the most preventable
Heartworm spreads through a single mosquito bite. The larvae travel to the heart and lungs, where adult worms grow up to 12 inches long. Left untreated, heartworm is often fatal. The dangerous part is that symptoms stay hidden for months, so most dogs look fine until the disease is advanced.
Prevention is simple: a monthly chewable, or an injection given every 6 or 12 months. Treatment is not. It is a months-long, costly, and risky process, often 10 to 20 times the price of a year of prevention, and it can run well over $1,000. In cats, there is no approved treatment at all, which makes prevention the only real option.
Signs to watch for in dogs include:
A soft, persistent cough
Tiring quickly on walks or during play
Reduced appetite and weight loss
A swollen belly in advanced cases
Because early heartworm hides so well, an annual test is the only reliable way to catch it. We include one in your pet's yearly wellness visit. You can see the full list on our clinic services page.
Fleas and ticks: more than an itch
Fleas and ticks are not just uncomfortable. A single flea can bite your pet up to 400 times a day, and a female lays up to 50 eggs a day. An infestation explodes within weeks. Fleas also carry tapeworm. Ticks in the Tampa Bay area can pass Lyme disease, ehrlichiosis, and other illnesses to pets and people. The ASPCA notes that in warm climates, ticks stay active all year.
Here is what to do at home:
Use a vet-recommended flea and tick preventive every 30 days, year-round
Check your dog for ticks after walks in tall grass or wooded areas
Wash bedding weekly during an active infestation
Treat every pet in the house at once, since fleas move between them
Building a prevention plan that fits your pet
The right products depend on your pet's size, species, and lifestyle. A house cat and a trail-hiking dog need different plans. We help you pick a combination that covers heartworm, fleas, and ticks with no overlap and no gaps. Most pets do well on a single monthly product that handles all 3. Puppies and kittens can usually start prevention at 8 weeks. Book a wellness visit to set up a plan, or request an appointment if your pet is overdue for a heartworm test.
When to call us
Call Gregory Veterinary Clinic if you notice any of these:

You have missed 1 or more months of your pet's preventive
Missing a dose is common. The fix is simple. Call us, and we will retest your pet and get them back on track.
Frequently asked questions
Do indoor cats need parasite prevention?
Yes. Mosquitoes and fleas get inside easily, and indoor cats still catch heartworm, with no treatment available once they do. Year-round prevention is the safest choice.
How often does my dog need a heartworm test?
Once a year, even on steady prevention. Testing confirms the medication is working and catches any gap early, which is why it is part of the annual wellness exam.
Can I buy prevention without seeing the vet?
Heartworm preventives are prescription products for a reason. Giving them to a dog that already has heartworm can be dangerous, so a quick annual test keeps it safe.
Year-round parasite prevention is one of the cheapest, highest-impact things you can do for your pet in Tampa. Call Gregory Veterinary Clinic in Carrollwood at (813) 592-7339 or request an appointment to set up a plan.
