Frequently Asked Questions


How do flea and tick chews work for dogs?

Flea and tick chews are formulated to work through your dog’s bloodstream. After your dog eats the chew, the active ingredients circulate in their system. When a flea or tick bites your dog, they ingest the medication and are killed quickly. This provides protection from the inside out, helping to control infestations and prevent future bites.

Are oral flea and tick treatments safe for my dog?

Yes, most oral flea and tick treatments are tested for safety and approved by veterinarians. It’s important to choose a product based on your dog’s size, age, and health condition. Always follow dosing instructions carefully and talk to your veterinarian if your dog has any underlying health issues or is taking other medications.

How long do flea and tick tablets last?

Many flea pills for dogs provide protection for about 30 days, though some formulas can last longer depending on the product. Monthly dosing makes it easy to maintain consistent protection year-round. Always check the specific guidelines for the product you choose to make sure your dog stays protected.

What is the difference between chews and topical treatments?

Chews work internally, circulating through your dog’s bloodstream, while topical treatments are applied to the skin and spread over the coat. Chews are often preferred for dogs who dislike topical applications or for owners who want a less messy option. Both can be effective; the best choice depends on your dog’s needs and your preference for application.

Do I need a prescription for flea and tick tablets?

Some flea and tick control for dogs, especially those that last longer or target multiple pests, do require a prescription. At PetPawsRx, we offer both prescription and non-prescription options and make it easy to submit your veterinarian’s information if needed, so you can get the right protection without the hassle.

How quickly do oral treatments start working?

Many oral flea and tick treatments start working within a few hours. Some products begin killing fleas within 30 minutes and can eliminate most pests within the first 24 hours. Full protection typically sets in quickly, helping to relieve your dog’s discomfort and prevent new infestations fast.

Can I give flea and tick chews to my puppy?

Some flea and tick chews are safe for puppies, but always check the age and weight requirements listed on the product label. Many oral treatments are approved for puppies as young as 8 weeks old and over a certain weight. Always talk to your veterinarian to choose a safe option for young dogs.
