Introduction
Living in Brooklyn with pets comes with unique joys—and unique risks. City pets share sidewalks, parks, and even apartment hallways with countless other animals, which means exposure to parasites, toxins, and illnesses is common. As a trusted Brooklyn animal hospital, St. Francis Animal Hospital sees these issues daily. Here’s what every pet parent should know about protecting their pet’s health in Brooklyn.
1. Fleas and Ticks in the City
Fleas and ticks aren’t just a “country” problem. In fact, in Brooklyn pet health cases, fleas are among the most common issues we treat—even for cats who never leave the apartment. Fleas can ride in on clothing or other pets in the building, and ticks can be found in green spaces like Prospect Park, Marine Park, and other outdoor areas. Left untreated, these pests can cause severe itching, skin infections, anemia, and spread diseases like Lyme.
While exact Brooklyn numbers aren’t tracked, citywide reports show that tick activity surged this summer — the NYC Department of Health even issued a 2025 Health Advisory on tick-borne diseases.
A national survey also found that 43% of indoor-only cat owners reported flea or tick problems. At St.Francis Animal Hospital Brooklyn, we’ve seen this trend firsthand — including several indoor cats with fleas this summer — proving that prevention is essential for every pet, not just those who go outside.
👉 Prevention matters. Our Brooklyn animal hospital carries trusted products like Revolution PLUS for cats and Simparica Trio for dogs to keep pets protected year-round.
2. Parasite Control Is a Must
Parasites like roundworms, hookworms, and tapeworms are not only harmful to pets but can also spread to humans. Dogs sniffing around tree pits, sidewalks, or shared yards in Brooklyn are at risk, while cats can contract parasites through fleas or contaminated litter. Parasite infestations often go unnoticed until pets show weight loss, diarrhea, or lethargy.
👉 Routine testing and monthly prevention are critical parts of pet health in Brooklyn. Our in-house pharmacy ensures your pet leaves protected the same day.
3. Urban Toxins and Hazards
The streets of Brooklyn hold hidden dangers for curious pets. Antifreeze leaks from cars, rodent bait in alleyways, cigarette butts, and discarded food can all pose toxic risks. Even small exposures can trigger vomiting, seizures, or worse.
👉 Supervision during walks is key, and if you suspect your pet has ingested something dangerous, contact St. Francis Animal Hospital Brooklyn immediately. Fast action can save lives.
4. Obesity in Apartment Pets
Many Brooklyn pets live indoors with limited outdoor play space. Add in busy schedules, and exercise often takes a back seat. As a result, obesity is one of the most frequent Brooklyn pet health concerns we diagnose. Overweight pets face higher risks of diabetes, arthritis, and shortened lifespans.
👉 Our team can design nutrition and activity plans that fit an urban lifestyle—whether it’s indoor play strategies for cats or safe exercise routines for dogs in city parks.
5. Dental Disease
Dental disease is often overlooked, but it’s one of the leading health issues for both dogs and cats in Brooklyn. By age 3, most pets already show signs of gum disease, and without care, this can progress to tooth loss, infection, or even organ damage. Bad breath, difficulty chewing, or pawing at the mouth are warning signs.
👉 As your neighborhood Brooklyn animal hospital, we provide professional dental cleanings and guidance on at-home care to prevent long-term problems.
Need to Know: Leptospirosis — A City Risk for Pets and People
Leptospirosis is a dangerous bacterial disease spread through rodent (usually rat) urine. In Brooklyn (and NYC more broadly), your dog doesn’t need direct contact with an infected rodent to get sick — stepping in contaminated water or soil, or licking paws after contact with a surface exposed to infected urine, is enough. The disease is zoonotic, meaning it can spread to humans.
What it can do in people:
– Early symptoms often mimic the flu: fever, headache, chills, muscle aches, vomiting, diarrhea.
– According to nyc.gov, if untreated, it can progress to kidney failure, liver damage, and respiratory complications.
– In NYC, 24 human cases were reported in 2023 — the most in a single year on record.
What it looks like in dogs:
– In 2023, there were 32 dogs diagnosed with leptospirosis in NYC, with 5 cases in Brooklyn alone.
– Among dogs with known vaccine histories, 91% were unvaccinated.
– According to an article by Cornell University College of Veterninary Medicine, signs to watch for are:
- Lethargy, weakness, or loss of appetite
- Vomiting, diarrhea, or abdominal pain
- Increased thirst or changes in urination
- Yellowing of the eyes or gums (jaundice)
- Coughing, difficulty breathing, or nosebleeds
- Muscle soreness or stiffness
👉 The leptospirosis vaccine is strongly recommended for all Brooklyn dogs. Protecting your pet protects your family.
