How to Choose OTC Dog Dewormers

Selecting the right OTC dewormer depends on your dog's individual needs and your comfort with administering medication at home.

Spectrum of Coverage

If your dog has a confirmed type of worm, a targeted formula may be more appropriate. For general prevention or unknown infestations, broad-spectrum options are often chosen.

Dog Size and Age

Using the correct product for your dog's weight and age ensures both safety and effectiveness. Puppies and small breeds may need special formulations.

Administration Method

Choose a format that matches your dog's preferences and your ability to administer the dose without stress.

Frequency and Routine

Adhering to the recommended schedule is important for successful deworming and minimizing the risk of reinfestation.

When to Consult a Veterinarian

If you're unsure about the type of worm or if your dog has ongoing symptoms, consult a veterinarian before starting any treatment.
