How to Choose Dog Flea and Tick Medications

Oral vs. Topical Treatments

Oral medications are usually given as tablets or chews, while topical solutions are applied along the back. Consider your dog’s tolerance and your own comfort with each method.

Dog Size and Weight

Selecting the correct dose for your dog’s size is crucial for both safety and results. Never use a product intended for a different weight class.

Activity Level and Lifestyle

Consider your dog’s daily activities. Dogs that swim or get bathed often benefit from waterproof or water-resistant products.

Pest Coverage Needs

If you live in an area with multiple pests, opt for a product that covers all relevant threats. Read labels carefully to understand the scope of protection.

Sensitivities and Allergies

If your dog has a history of skin or digestive sensitivities, choose gentle or fragrance-free formulas and observe closely after application.

FAQ For Dog Flea And Tick Medications
