Large and giant breed dogs: safe, accurate dosing
Introduction
Big dogs burn through calendars faster and drift between weight bands with training or seasons. Accurate dosing and a simple reminder system keep protection steady all year.
How to stay accurate
-
Re-weigh every 1–2 months, and after any training or diet changes.
-
Match the current weight band at purchase and dosing.
-
Do not combine or split chews unless your vet has advised a specific plan.
-
Keep a dosing record in your phone or on a whiteboard for multi-dog homes.
Format choices for big dogs
-
Chews are unaffected by bathing and swimming, which suits active dogs.
-
Collars can be an alternative if worn continuously and fitted correctly.
Choose what you can give on time, every time.
Travel, sport and kennels
-
Dose a few days before trips so protection is active.
-
Pack the next dose if travel overlaps the due date.
-
After bush or beach days, do a full tick check that night and the next morning.
Safety basics
-
Dog products for dogs only.
-
Check minimum age and the weight band ceiling on packs. If your dog sits above a labelled band, ask your vet for an exact plan.
-
Avoid stacking multiple preventatives unless your vet advises.

Dose to today’s weight and ask your vet if you’re consistently between sizes.
We swim and work outdoors. Will protection still hold?
