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.
Fipronil (9.7% m/v)
Quite cheaper than the one my vet recommended. It seems to be working fine.
