Collection: Dog Flea & Tick Prevention

Fleas and ticks are more than an itchy nuisance. Fleas can cause skin irritation, allergic reactions and tapeworms, and they multiply quickly once they're in your home. Ticks can carry serious illnesses, including Lyme disease, ehrlichiosis and anaplasmosis. Consistent flea and tick prevention is one of the most important things you can do to protect your dog's health. At T-Rex Pets, our dog flea and tick collection includes flea and tick collars, spot-on treatments, flea shampoos, sprays, flea combs and home and yard products to help you stop pests before they become a problem.

Why Year-Round Prevention Matters

Many people think of fleas and ticks as a summer problem, but in many parts of the US they're active for much of the year. Fleas can live and breed indoors through winter, and some ticks stay active whenever temperatures rise above freezing. Most vets recommend year-round prevention, because it's much easier to prevent an infestation than to get rid of one. A single missed month can give fleas the chance to settle into your carpet, furniture and your dog's bed.

Understanding the Flea Life Cycle

The fleas you see on your dog are only a small part of the problem. Adult fleas lay eggs that fall off into carpets, bedding and furniture. Those eggs hatch into larvae, which spin cocoons and become adults that jump back onto your dog. Because eggs and pupae hide in your home, a complete flea plan usually treats your dog, your home and sometimes your yard. Pupae can survive for weeks, which is why it can take a couple of months of consistent treatment to fully break the cycle.

Types of Flea and Tick Products

Flea and Tick Collars

Modern flea and tick collars release active ingredients slowly over several months. They're low-maintenance and a good option for owners who want long-lasting protection without monthly applications. Choose the right size and fit, and remove the collar if you notice skin irritation.

Spot-On Treatments

Topical spot-on treatments are applied to the skin between the shoulder blades, usually once a month. They spread across the skin's oils to kill or repel fleas and ticks. Always choose the product matched to your dog's weight range.

Flea Shampoos

Flea shampoos kill fleas on contact and give fast relief during an active infestation. They don't usually provide long-term protection, so follow up with ongoing prevention. Browse gentle everyday options in our dog shampoo collection.

Flea and Tick Sprays

Sprays offer quick, targeted protection before hikes and outdoor adventures and can be used between other treatments when the label allows.

Flea Combs

A fine-toothed flea comb is the easiest way to check for fleas and flea dirt. Comb near the base of the tail and belly, and wipe the comb on a damp white paper towel. Dark specks that turn reddish are flea dirt.

Home and Yard Treatments

Home sprays, carpet powders and yard treatments help kill fleas at different life stages where they hide. Use them alongside on-dog prevention for an infestation.

Oral Prescription Preventives

Many vets recommend oral chewable flea and tick preventives, which require a prescription. Ask your vet which option is best for your dog's lifestyle and health.

How to Choose the Right Flea and Tick Protection

• Weight and age: Most products are dosed by weight and have a minimum age. Using the wrong size can be ineffective or unsafe.

• Lifestyle: Dogs that hike, swim, visit dog parks or live near woods need strong tick protection. Swimmers may need a water-resistant product.

• Your region: Tick-borne diseases are more common in some areas. Your vet can advise on local risks.

• Health history: Dogs with flea allergies, skin conditions, seizures or other health issues need vet guidance.

• Other pets: Treat every pet in the home. Some dog flea products, especially those containing permethrin, are toxic to cats, so never use a dog product on a cat.

Signs Your Dog Has Fleas or Ticks

• Scratching, biting or licking, especially around the tail, hips and belly

• Small dark specks of flea dirt in the coat

• Red bumps, scabs, hair loss or hot spots

• Visible fleas moving through the fur

• A small bump that turns out to be an attached tick, often around the ears, neck, armpits or between toes

How to Remove a Tick Safely

Use fine-tipped tweezers or a tick removal tool. Grasp the tick as close to the skin as possible and pull upward with steady, even pressure. Don't twist, squeeze or burn the tick. Clean the area, wash your hands and watch the spot for redness or swelling. If your dog becomes lethargic, lame or feverish in the weeks after a tick bite, see your vet.

Treating Your Home

• Wash your dog's bedding in hot water weekly during an infestation. Find replacements in our dog beds collection.

• Vacuum carpets, furniture and car seats often, and empty the vacuum outside.

• Use a home flea spray or carpet treatment made to kill eggs and larvae.

• Keep grass short and clear leaf litter where ticks like to wait.

Soothe Itchy Skin After Fleas

Flea bites can leave skin irritated even after the fleas are gone. Gentle oatmeal shampoos and products from our dog skin and coat collection can help support skin as it recovers. If your dog has flea allergy dermatitis or open sores, talk to your vet.
