A friend just recommended this one to me because Toby boy has tapeworms. She uses this one every three months on her gang:
NEW Drontal allwormer chewables up to 10kg(up to 22lbs) 2 tabs
NEW Drontal allwormer chewable is Palatable, all pupose intestinal wormer for dogs, its tasty liver flavour is a real treat for your dog plus it has the same active ingredients as the original market leading Drontal allwormer. Praziquantel, Pyrantel embonate and Febantel
We recommend worming your dog every 3 months. I order it from:
Dog supply, Pet meds, Pet medication, Pet medicine at Equine-Mega-Store online pet supply store
