Adventure on, pests off — an independent K9 Advantix II guide. Not Elanco, and not the brand's official site.
Start at the scale

Policy

If the box comes back

Wrong band for the dog on the scale, or a vet said switch — returns run entirely on the retail partner's policy for the listing you bought.

Start from your orders page with the partner; labels, refunds and timelines are theirs from first click to closed case.

One field note: weigh the dog before ordering, not after opening. Topicals in opened boxes return poorly everywhere, and the sizing guide exists so the first box is the right one.

If a listing steered you wrong, tell the guide anyway — the card that misled you gets re-read and rewritten.
