On the weight limit

4kg is the ceiling Johnson's give for this particular size, and going over it isn't a case of "close enough" — a dog that's grown past that weight, or a puppy you're not sure about, needs the correct size for their actual weight rather than this one stretched to cover it.

Why we chose it

Small dogs and puppies get overlooked by flea products built around a bigger average dog, and this one is sized specifically for the under-4kg bracket. Two vials also means you're covered for two months from a single purchase.

— Matt, founder

Specifications

Brand: 4Fleas

Full description

A small dog or puppy under 4kg is the trickiest weight bracket for flea treatment, because a lot of products are built around an adult dog's dosing and simply don't have a version scaled down far enough — which is exactly the gap this one is sized for.

It's a fast-acting spot-on containing imidacloprid, applied to the skin, and Johnson's say it kills fleas on contact on the dog and in the surrounding area, with up to two months of protection from the pack. It comes as two vials, each giving up to four weeks of cover, and it's specifically for dogs and puppies up to 4kg, over 8 weeks of age.

On the weight limit. 4kg is the ceiling Johnson's give for this particular size, and going over it isn't a case of "close enough" — a dog that's grown past that weight, or a puppy you're not sure about, needs the correct size for their actual weight rather than this one stretched to cover it.

Who it's for: owners of a puppy or small adult dog under 4kg starting flea protection, who want two full treatments in one pack rather than buying single doses.
