Vets usually recommend monthly application if you are managing flea allergy dermatitis or an active infestation. Dosages are available for dogs of all sizes, from small breeds up to extra-large. Puppies can be treated from 8 weeks old, as long as they weigh at least 2kg. Effective duration: around 2 months for fleas, up to 1 month for ticks - Any new fleas landing on the dog are eliminated within 24 hours. - Effectively controls biting/chewing lice infestations **Dosage guides** - 2–10kg: 0.67ml pipette - 10–20kg: 1.34ml pipette - 20–40kg: 2.68ml pipette - 40–60kg: 4.02ml pipette - Over 60kg: two 2.68ml pipettes combined **Warnings** - Bathing or shampooing up to 1 hour before application does not affect the product’s effectiveness - Do not bathe your dog or let them swim for two days after application - Weekly bathing with a gentle, soap-free shampoo won’t affect protection — avoid bathing more often than once a week, and skip skin-softening shampoos - Outdoor dogs or those in wildlife areas are at higher risk of fleas and ticks - The dose is calibrated to dog bodyweight, and using it on a cat risks overdosing. *Dealing with a flea problem at home?
