Giant Flea, Tick & Worming4 products

Giant-breed flea, tick, and worming treatments cover the largest dog bracket — Great Danes, Saint Bernards, Newfoundlands, Mastiffs, and Bernese Mountain Dogs. Bravecto XL, Nexgard Spectra Red, and Simparica Trio for 40.1-60kg dogs dominate this space. Some giant dogs sit at the upper edge of available dose brackets, and very large dogs over 60kg may need combination dosing — check product guidance carefully, and ask your vet if unsure.
