We’ll talk about ProMeris for Dogs – a flea and tick infestation treatment that claims to start killing the little beasts within four hours of application and kills most of them by 24 hours. Is it any good? Should you be using it? Read on.

ProMeris for Dogs was discontinued in 2011, but is unfortunately still available to purchase on many websites.

Active Ingredients

ProMeris for Dogs consists of the following ingredients –

Product Warnings and Side Effects
