FRONTLINE® SPOT ON for dogs is the original formula from the UK’s leading flea and tick brand*, FRONTLINE®. It kills fleas and ticks on your dog to help protect them from the discomfort and diseases these parasites cause. Use it every 4 weeks for optimal protection.**


• Kills fleas on your dog within 24 hours
• Kills ticks within 48 hours, helping to reduce the risk of tick-borne disease
• Kills lice


FRONTLINE® SPOT ON is a clinically proven veterinary medicine that’s available in 1-dose, 3-dose and 6-dose packs. It can be applied to dogs from 8 weeks of age that weigh at least 2 kg. It can also be used on pregnant and lactating dogs.


FRONTLINE® SPOT ON is a topical treatment which goes over your dog’s skin and hair to kill fleas and ticks through contact with them – they don’t have to bite your dog to be killed. Bathing/shampooing/ water exposure once a week does not affect the product’s effectiveness. Do not bathe your dog or let them swim for 2 days after application.


If your dog is unwell, please see your vet for advice before you apply a flea treatment.

Active Ingredients: Fipronil 134mg


FRONTLINE® SPOT ON for Dogs is not suitable for use on rabbits.

Frontline spot on flea drops

by Charlotte -

These flea drops are easy to use and I like the stickers you get to stick on your calendar for a reminder! Stored well but easy to open and no mess. I use these all the time for my dog :)

Seems to work for ticks, not fleas

by Wexfordshopper -

Our dog caught fleas last year despite using Frontline and I could not get rid of them for about 2 months despite spraying the whole house etc. It was only when I switched to Advantage that we got rid of the damn things. Apparently fleas are now immune to Fipronil the active ingredient in Frontline. However it still seems to work for ticks, which Advantage doesn't do so I now use both. Therefore only giving 3 stars.
