Florida’s Hidden Threats: Parasites Every Pet Owner Should Watch For
You take every step to keep your pet happy and healthy, from the best food to daily walks. But have you ever wondered why your pet is suddenly scratching more than usual, or suddenly has diarrhea? For those of us with pets in Florida’s warm, humid climate, the risk from parasites like heartworms, fleas, and ticks is a constant concern. It’s a risk that requires year-round vigilance to protect your animal from infection and serious disease. Routine checkups and consistent parasite control are the keys to keeping these dangers under control, no matter the season.
At Bayview Animal Hospital in Saint Petersburg, we understand how challenging it can be to protect pets in Florida’s tropical environment. Parasites thrive here all year long, and early detection is essential. Our services include advanced diagnostics, in-house lab testing, and personalized prevention strategies designed to keep your dog or cat safe and comfortable. We take care of pets like our own- because only the best will do.
Understanding Florida’s Parasite Risks for Pets
Fleas, ticks, mosquitoes, and intestinal worms are more than a nuisance. They can spread diseases that affect both pets and people. Warm weather means there’s no “off-season” for prevention in coastal Florida. Many pet owners first notice parasites after spotting tiny specks on fur, finding worms in stool, or seeing unexplained scratching.
Preventive care through routine wellness exams makes it easier to identify risks before symptoms appear. If you notice your pet acting differently, vomiting, losing weight, or showing signs of fatigue, schedule an appointment so we can rule out parasite-related causes.
Why Year-Round Parasite Protection for Your Pet is Essential
Even when temperatures drop slightly in winter, parasite eggs and larvae can survive in soil, carpets, and bedding. Mosquitoes, the carriers of heartworm, remain active on mild days, while fleas continue reproducing indoors. Regular preventive medication ensures a consistent barrier against infection.
Comprehensive year-round parasite prevention also helps avoid infestations that are difficult to control once established. At Bayview Animal Hospital, we recommend keeping your pet on prevention every month, all year long, with annual testing to confirm protection is working effectively.
Fleas: Tiny Pests with Big Consequences for Pets
Fleas multiply rapidly, and once indoors, they can live in carpets, bedding, and upholstery for months. Beyond itching, they cause allergic reactions, anemia in small pets, and can transmit tapeworms. Flea allergy dermatitis is one of the most common issues we see, causing intense irritation and skin infections.
If your pet scratches constantly or develops hair loss, our team can use diagnostic testing to confirm the cause and create a treatment plan. Managing fleas requires both medical prevention and environmental cleaning, washing bedding, vacuuming thoroughly, and treating the home environment when needed.
Don’t forget- ALL pets need prevention, not just those who go outside. A flea can easily jump on your dog and hitchhike home to your indoor cat- and if they aren’t on a flea preventative, those fleas will make your home their own. Once you have a flea infestation, the life cycle can be hard to break. One flea can lay hundreds of eggs in just a few days.
For pets with sensitive skin or allergies, our veterinarians can also recommend laser therapy to help reduce inflammation and promote healing after infestations.
Ticks and Tick-Borne Diseases in Pets
Ticks thrive in grassy and wooded areas but are just as likely to be found in suburban backyards. They can transmit Lyme disease and other illnesses within hours of attachment. Daily checks after outdoor activity and maintaining trimmed lawns can greatly reduce exposure.
Regular tick prevention helps protect pets from bites, while using safe products and checking for parasites remains essential. Our veterinarians tailor advice to local risks here in coastal Florida, where warm weather and lush landscaping allow ticks to thrive year-round.
During annual wellness exams, we screen for tick-borne disease and help select preventive options best suited to your pet’s lifestyle. If you find a tick or suspect exposure, contact us online or call us for an appointment.
Intestinal Worms and Giardia in Pets
Many pet owners are surprised to learn that puppies, kittens, and even indoor-only pets can harbor intestinal worms. Intestinal parasites such as roundworms, hookworms, whipworms, and tapeworms cause bloating, vomiting, diarrhea, and nutritional deficiencies. Most pose a zoonotic risk to humans, meaning those sloppy puppy kisses could be transmitting parasites to your family.
Giardia is another parasite that thrives in warm, moist environments. Pets become infected by ingesting contaminated water or grooming after outdoor play. Because giardia can cause persistent diarrhea and dehydration, fecal testing is vital for accurate diagnosis.
Our in-house lab allows us to detect these parasites quickly and begin effective deworming and hydration therapy. Regular fecal exams, especially for younger pets, are an important part of lifelong preventive care.
Heartworm Disease in Pets: A Year-Round Concern
Mosquitoes transmit heartworm, and because they are active throughout Florida, every pet is at risk. These worms grow inside the heart and lungs, causing coughing, fatigue, and even heart failure. Cats can suffer respiratory distress even from a few worms.
The latest heartworm prevalence map shows that cases remain common across the Southeast, making prevention essential. Treatment is lengthy and expensive for dogs and unavailable for cats, so consistent monthly prevention combined with annual testing is the only safe strategy.
During your pet’s next wellness visit, we’ll check for heartworm, review your prevention plan, and help you choose a product that fits your household and lifestyle.
Mites and Skin Health in Pets
Mites are microscopic parasites that can cause significant discomfort and hair loss in both dogs and cats. Mites in dogs may cause mange, leading to patchy bald spots and severe itching. Mites in cats often appear as ear irritation, dark discharge, or excessive scratching.
Left untreated, these conditions can lead to bacterial or fungal infections. Some mites can even be contagious to humans. At Bayview Animal Hospital, we use skin scrapings and cytology to confirm the cause, followed by safe prescription treatments that target mites while soothing irritated skin.
Trematodes and Lung Flukes in Pets
While rare, trematode infections and lung fluke infections can occur in pets that eat raw fish, frogs, or crayfish, common exposures in coastal regions like ours. These parasites may cause coughing, respiratory distress, or chronic pneumonia. Diagnosis often requires X-rays or ultrasound to locate cysts in the lungs.
Our diagnostic imaging capabilities help us identify these infections quickly, and we provide treatment and follow-up care to monitor your pet’s recovery. If your dog or cat develops unexplained coughing or breathing changes, don’t wait, book an appointment right away.
Commom Pet Parasites That Also Affect People
Many pet parasites are zoonotic, meaning they can spread to humans. Zoonotic parasites like roundworms, hookworms, and giardia can cause skin rashes, organ damage, or gastrointestinal illness in people, especially young children and those with compromised immunity.
Maintaining good hygiene, washing hands before eating, and wearing shoes outdoors all reduce the risk. Don’t walk barefoot in places that your pet has defecated, and avoid letting your pet lick your face. Regular veterinary checkups protect both your family and your pets. Our team works with families to create prevention strategies that protect every household member, furry or otherwise.
How Veterinarians Detect Parasites
Detecting parasites early often requires specialized testing. We perform fecal exams to identify intestinal worms, bloodwork for heartworm and tick-borne diseases, and skin or ear cytology for mites. Digital imaging, such as X-rays and ultrasound, helps locate hidden internal parasites.
Routine screenings at Bayview Animal Hospital ensure your pet stays healthy and parasite-free. If we find anything concerning, we’ll discuss treatment options and preventive steps to stop reinfection.
A Better Way to Protect Your Pet from Parasites
