FAQs

Please read our FAQs page to find out more about PetMax.

What is Advantage II for Large Dogs?
It's a topical, monthly flea treatment for large dogs. Pre-measured, fragrance-free application tubes apply to the skin between the shoulder blades. Kills fleas through contact — they don't have to bite to die.
What's in it?
Two active ingredients: imidacloprid kills adult fleas on contact, and pyriproxyfen is an insect growth regulator that prevents flea eggs and larvae from developing. Together they break the flea life cycle.
How fast does it work?
Starts killing fleas within 12 hours of application and protects for up to 30 days per dose. Reapply monthly for continuous coverage.
What size dog is 'Large'?
Check the package — Bayer/Elanco's 'large' Advantage II tube is sized for a specific weight range (typically 21–55 lbs / 9.5–25 kg). Size matters because dosing is based on body weight; using the wrong size means under- or over-dosing.
Do I need a prescription?
Advantage II is over-the-counter (no prescription needed). Still worth talking to your vet first if your dog has health conditions, is pregnant, or is on other medications.
