Asked at the trailhead

Is this the official K9 Advantix II site? No — it's an independent catalog and field guide. Elanco's own product page and the label in the box are the official word.

My dog is right at 20 pounds — which band? The scale decides, not the estimate: weigh the dog, and if the reading sits on a boundary, ask your vet rather than rounding. Dosing bands exist for a reason.

Why is there no cat version here? Because there must never be one — K9 Advantix II contains permethrin, which is toxic to cats. The safety guide covers what that means for households that have both.

Puppies? The label allows dogs and puppies 7 weeks and older, inside the right weight band. Younger or lighter than that — vet first.

Why do the bigger boxes cost less per dose? Same math as anywhere: a six-dose box runs about $13 a month against nearly $18 in the two-dose — the dosing table lays out every band's numbers.

The 12-dose bundle disappeared — will it return? Stock is the retailer's call. When a listing loses its buy box for good, it leaves the shelf here on the next update.
