My golden retriever, who weighs 52kg, has been on Simparica Trio for three months. We’ve seen fewer flea sightings at home and no tick issues. The pork flavour is a hit with him. Even after swimming, the protection still works. No side effects reported.
Phil Fraser –
Great product for a large breed dog. The chew is easy to give and he enjoys the taste. We noticed fewer flea bites and no signs of tick infestation. Works well even after a bath.

My dog was diagnosed with roundworms last month. After switching to Simparica Trio, the worms were under control. The monthly chew is convenient and he doesn’t resist it. Protection against heartworm is a relief.
