Verified Purchase(What is this?)
This review is from: Bob Martin Double Action Spot on for Medium Dogs Under 10 Kg (Misc.)
I use this regularly as a preventative treatment on my two terriers and in five years have only ever seen one flea... and that critter looked very unwell! Treatment is easy to apply, doesn't make dogs itch and isn't greasy like some other flea products. Note that each treatment does only last 4 weeks. (The front of the box is a bit misleading as says it gives 12 weeks cover, but that's for ALL THREE ampules together).
