Fiprotec is a powerful flea and tick treatment for dogs and puppies 10 weeks of age and above. It is formulated as a topical spot-on solution that kills fleas and ticks present in dogs and controls flea allergy dermatitis. One application of Fiprotec kills fleas for up to 2 months and ticks for up to 1 month. It contains fipronil as its active ingredient which provides a residual activity as it gets stored in the oils of skin and hair follicles and continues to be released onto the skin and coat quickly.
Quite cheaper than the one my vet recommended. It seems to be working fine.
