Fleas and ticks don't wait for a convenient moment, and a spot-on that only needs applying once a month is built around that fact — it's protection you set and largely forget about, rather than something you have to remember weekly.

FleaSolve's spot-on contains 402mg of Fipronil per application, applied to the back of the neck with a pipette using the standard topical spot-on method. It's positioned for monthly preventative use, giving four weeks of protection against fleas and eradicating and guarding against ticks, including Ixodes Ricinus, the species that carries Lyme disease.

One thing worth flagging. Our own maker lists this pack under one name while its own product code points to a different dog-size banding, so treat the exact weight range as unconfirmed and check the pack's own label for the size it's intended for before applying it.

Who it's for: owners looking for a monthly, vet-strength Fipronil spot-on for a large dog, wanting cover against both fleas and ticks from one application rather than two separate products.
