Capstar - Fast Acting Oral Flea Treatment
产品描述
TL;DR: Capstar is a fast-acting oral flea tablet that starts killing adult fleas within 30 minutes, giving dogs rapid relief during an active infestation. It's a short-term knock-down treatment — not a long-term preventive — available in two variants sized for small or large pets.

Who is it for?
Capstar is for dog owners in the GTA dealing with a visible flea infestation who want fast relief before starting a longer-term routine. The Large Dogs variant is intended for pets over 25.1 lb, while the Small Dogs & Cats variant covers lighter pets from 4 weeks of age.
Choose the variant that matches your pet's body weight at checkout. It's a useful addition to any household kit where multiple pets may share bedding or outdoor space.
Feeding & use
Give one tablet matched to your pet's weight category, either directly by mouth or mixed into a small portion of food. If new fleas appear after treatment, you can repeat the dose once per 24 hours.
Because Capstar is a knock-down treatment rather than a preventive, follow up with a longer-acting product to help reduce re-infestation.
What should you use alongside Capstar?
If you're building out an ongoing flea and tick prevention routine, consider Advantix II - Flea & Tick Medicine or Advantage II - Flea & Tick Medicine for dogs, and Advantage II - Flea & Tick Medicine for smaller cats and kittens in the household.
Capstar pairs well with a monthly topical so you stay covered beyond the initial knock-down.
Available for same-day pickup at our North York, Toronto storefront, or ships Canada-wide.
