How often to use flea treatment on dogs
Introduction
How often should you flea-treat your dog? Most modern products are monthly. Some last longer. The right interval depends on the brand, your dog’s lifestyle, and whether you want broader parasite cover. The safest plan is to pick a reliable product, match the weight band, and stick to the label schedule.
The simple rule
Follow the label interval for your chosen product. If you use different products for different parasites, follow the shortest interval so you do not leave gaps.
Choosing an interval that fits your routine
Chews are easy for swimmers and beach dogs because bathing does not affect them. Spot-ons can suit fussy eaters but need a dry period after application. Long-acting chews reduce how often you need to remember to dose. Choose the format that you can give on time, every time.
What if you miss a dose?
Give the dose as soon as you remember. Then set your future reminders from today. If you missed for more than a few weeks, treat all pets and refresh the house clean-up. Expect to see a few fleas while the home environment catches up.
Puppies and small dogs
Check the minimum age and weight on the pack before starting. Re-weigh growing pups often and move to the next weight band when they outgrow the current one.
Year-round control in Australia
Fleas can persist indoors in many Aussie homes. Year-round dosing prevents flare ups and protects dogs that react strongly to bites.

FAQ
Is monthly always enough?
Yes for many homes when used on time. In high-risk areas or mixed pet homes, consistency and house cleaning matter as much as product choice.
I bathe my dog weekly. Will a spot-on still work?
Follow the label on bathing and swimming. If frequent baths are part of your routine, a chew can be simpler.
