By Dr. Duncan Houston BVSc

🐶 Introduction: Why Flea & Tick Prevention Still Matters

Fleas and ticks aren’t just seasonal pests—they’re year-round threats in many regions. From itchy skin to serious diseases like Lyme or tapeworms, these parasites pose real risks. That’s why every dog, whether in the city or countryside, needs a tailored prevention plan. As a veterinarian, I’m here to help you navigate the safest and most effective options for 2025. 🏥

In this article, you’ll learn:

• ✅ Vet-recommended flea and tick products by type
• 🔹 How to choose the right formula for your dog’s age, weight, and lifestyle
• 🦴 Tips for year-round protection and product rotation
• 🚀 How Ask A Vet, 

1. Oral Flea & Tick Medications 💊

These chewables or tablets offer systemic protection and are often a top choice for dogs who swim or dislike topical products.

• NexGard: Monthly chew that kills fleas and ticks quickly. Safe for puppies 8 weeks+ and 4 lbs+.
• Simparica Trio: Covers fleas, ticks, heartworm, and intestinal worms in one chew. Great for broad-spectrum protection.
• Credelio: Fast-acting chewable with a mild flavor profile—ideal for picky eaters.

2. Topical (Spot-On) Treatments 💧

Applied to the skin, these treatments spread through oils on your dog's coat. They're a good alternative for dogs with sensitive stomachs or pill aversions.

• Frontline Plus: Longtime vet staple for killing fleas, ticks, and lice. Waterproof 24 hours after application.
• K9 Advantix II: Repels and kills fleas, ticks, and mosquitoes—not for cats or homes with cats.
• Revolution Plus (Rx): Covers fleas, ticks, heartworm, and ear mites—especially good for small breeds.

Vet Tip: Avoid bathing 48 hrs before or after application for maximum effectiveness. 🛁

3. Flea & Tick Collars 💳

Modern collars offer long-lasting, low-maintenance protection—ideal for dogs with minimal grooming needs or for owners who prefer set-it-and-forget-it solutions.

• Seresto: Offers 8-month protection against fleas and ticks. Odorless, adjustable, and water-resistant.
• Vetality Protect: Over-the-counter collar option with natural oils and moderate protection.

Vet Tip: Check collar fit monthly, especially on growing puppies. 🧤

4. What’s Best for Your Dog? 🧍

• 🐶 Puppies (8–12 weeks): Start with a vet-approved oral (NexGard, Simparica) or spot-on suited to weight.
• 🌊 Swimmers: Oral meds or waterproof collars like Seresto
• 🏠 Indoor dogs: May do well with topicals or low-dose collars
• 🧠 Sensitive pups: Stick to single-spectrum meds; avoid multi-action until tolerated

Ask A Vet can help you choose what’s safest based on breed, allergies, and medical history.
