Parasite Prevention for Dogs

Why Parasite Prevention Matters

Parasites such as fleas, ticks, and heartworms can cause itching, infections, and serious health issues. Untreated infestations may lead to anemia, skin infections, or tick‐borne diseases. Protecting your dog with a reliable prevention plan helps avoid costly vet visits and keeps your pup comfortable and active year‐round.

Our Best‐Selling Products

We carry top brands that don't require a prescription, including Advocate, Bravecto, Milbemax, NexGard, NexGard Spectra, Simparica, and Simparica Trio. NexGard® and Simparica® chewables provide monthly flea and tick control, while NexGard Spectra® also covers heartworm and intestinal worms. Bravecto® and Advocate® offer longer‐lasting protection in topical or collar form, and Milbemax® tablets guard against multiple worm types. Simparica Trio® combines protection against fleas, ticks, heartworm, and worms in a single chew.

Choosing the Right Plan

Select a product based on your dog's age, weight, and lifestyle. Outdoor dogs face higher parasite risks, but indoor pets still need protection—fleas can hitch a ride on clothing, and mosquitoes carry heartworm. Consult each product's label for age and weight guidelines, and talk to your veterinarian if your dog has preexisting health conditions.

Administration & Safety Tips

Follow each product's directions: Bravecto® topical applications occur every 12 weeks, while Milbemax® tablets are given every 4 weeks. Wait at least 48 hours after applying most topical treatments before bathing your dog to ensure full absorption. Our blog offers step‐by‐step application guides and reminders to help you stay on schedule. If you have questions, our customer support team is ready to assist.

Monitoring & Follow‐Up

Keep an eye on your dog's coat and skin for signs of fleas—look for small black specks or excessive scratching. Check for ticks regularly, especially after outdoor activities. Schedule annual veterinary checkups and ask for a heartworm test before starting a new prevention product. Early detection and consistent follow‐through help maintain your dog's long‐term health.

Frequently asked questions

How often should I give my dog parasite prevention?
Most treatments are administered monthly, while some collars or topical products last up to 8–12 weeks. Always follow label instructions.
Can I use the same product on puppies and senior dogs?
Not always—age and weight restrictions vary by product. Check each label carefully to ensure safety for your dog's life stage.
What signs indicate my dog might have a parasite?
Look for excessive scratching, small black “flea dirt,” coughing (heartworm), or visible worms in stool.
Is it safe to bathe my dog after applying topical treatment?
Wait at least 48 hours after application to allow the medication to absorb fully; refer to product guidelines for specifics.
Do I need a vet's prescription for these products?
Our best sellers are non‐prescription, but consult your veterinarian if your dog has health concerns or you need tailored advice.
