Tick Prevention for Pets in Missouri

Missouri's diverse tick population poses real health risks to pets, not just people. Dogs are highly susceptible to tick-borne diseases including Rocky Mountain Spotted Fever, ehrlichiosis, anaplasmosis, and Lyme disease. Cats can also carry ticks into the home, potentially exposing family members. A comprehensive approach to tick prevention for pets combines year-round tick prevention products, regular tick checks, and yard management.

Tick-Borne Diseases in Missouri Pets

The diseases Missouri ticks carry affect dogs with varying severity:

• Rocky Mountain Spotted Fever: Can be rapidly fatal in dogs if not treated; symptoms include fever, lethargy, loss of appetite, and sometimes a rash or swelling in the limbs
• Ehrlichiosis: Common in Missouri dogs; causes fever, weight loss, bleeding disorders, and in chronic cases can cause serious long-term health problems
• Anaplasmosis: Symptoms similar to ehrlichiosis; treatable with antibiotics when caught early
• Lyme disease: Less common in Missouri than in northeastern states but present; causes joint pain, fever, and fatigue in dogs; some dogs develop serious kidney complications

Cats are less commonly diagnosed with tick-borne disease but can carry ticks into the home and act as a vehicle for bringing ticks to family members.

Tick Prevention Products for Dogs

Consult your veterinarian for specific product recommendations, as the best option depends on your dog's age, weight, health status, and lifestyle. General categories include:

• Oral tick preventives (monthly or 3-month chewables): Products containing isoxazoline compounds (e.g., fluralaner, afoxolaner, sarolaner, lotilaner) are highly effective, kill ticks quickly after attachment, and are not washed off. These are currently among the most effective tick prevention options for dogs.
• Topical spot-on treatments: Applied monthly between the shoulder blades; effective but can be washed off with frequent bathing. Products containing permethrin (for dogs only — never use permethrin on cats) provide repellent and kill activity.
• Tick collars: Some collars (particularly those containing flumethrin and imidacloprid) provide months of protection. Effectiveness varies by brand and product — veterinarian guidance is recommended.
• Lyme vaccine: Available for dogs in areas with Lyme disease risk; may be appropriate for dogs with high outdoor exposure in wooded areas

Tick Prevention for Cats

Tick prevention for cats requires special caution — many products safe for dogs are highly toxic to cats, including permethrin. Never use dog tick prevention products on cats. Cats require specifically formulated feline products. Consult your veterinarian before using any tick prevention product on a cat.

How to Check Your Pet for Ticks

Even with prevention products, regular tick checks after outdoor time are important — no product is 100% effective, and finding and removing ticks promptly reduces disease transmission risk. Check your pet thoroughly after time in wooded, grassy, or brushy areas:

• Run your fingers through the coat against the direction of hair growth, feeling for small bumps
• Pay particular attention to: around the ears and ear canals, between the toes, around the tail base, in the groin area, and under the collar
• In dogs with thick or double coats, part the fur in sections to check the skin surface
• Use a fine-toothed flea comb to help find small ticks (nymphs, seed ticks)

Tick Removal from Pets

Remove ticks from pets the same way as from humans — fine-tipped tweezers grasped close to the skin, steady upward pull without twisting. Do not use petroleum jelly, nail polish, or heat. After removal, disinfect the bite site and your hands. Monitor the bite area and your pet's health for signs of illness over the following weeks.

Yard Management for Pet Protection

If your dogs spend significant time in the yard, reducing tick populations in the yard directly reduces your pets' tick exposure. Professional barrier treatment targeting low vegetation, leaf litter, and ground cover significantly reduces tick populations in the areas where pets spend time. Combined with effective on-pet prevention products, yard treatment provides a strong two-layer defense for your pets and your family.
