Best flea treatment for large dogs in Australia

Introduction

Large dogs need accurate weight-banded dosing and a format that fits their routine. The goal is year-round comfort with a plan you will not miss.

What to look for

• Correct weight band. Re-weigh if your dog’s condition changes. Never mix packs to “average out” a dose.

• Format fit. Chews suit swimmers and bath lovers. Collars give on-pet cover if fitted and worn all the time.

• Scheduling. Monthly habits are easy to stack with pay cycles or bills. Longer-acting options reduce how often you need to remember.

• Whole-house approach. Treat every pet, and keep a simple cleaning routine if fleas are already in the home.

Chew, collar, or spot-on?

• Chews: reliable for active and water-loving dogs; not affected by bathing.

• Collars: long acting if fitted correctly and worn continuously.
  Pick the format you can give on time, every time.

Dosing and reminders

Most chews are monthly. Some last longer. Set a phone reminder and tie dose day to an easy date. If you use different products for different parasites, follow the shortest interval so you do not leave gaps.

Safety checks

• Dog products for dogs only.

• Match weight band and minimum age every time.

• Do not stack different flea and tick products unless your vet advises.

• Ask your vet first if your dog is pregnant, breeding, unwell, or on other medicines.

FAQ

My dog is a giant breed. How do I choose the right pack?
Use the pack that matches today’s weight. If needed, your vet can advise on using multiple packs safely. Do not guess or split chews.

We swim every weekend. Will a chew still work?
Yes. Chews are not washed off by bathing or swimming.

Can I switch products later?
Yes. Start the new product when the old one is due to avoid gaps.
