What is Stronghold for dogs and cats?

Stronghold is the same product as Revolution, which is known by different names in different parts of the world. It is produced by the same manufacturer and contains the same active ingredients.

Stronghold spot-on is a topical treatment that provides broad spectrum parasite protection for your dog or cat. Stronghold is designed to make caring for your pet easier by preventing the development of heartworm disease, controlling flea infestations and treating ear mites. It also treats tick infestations and sarcoptic mange in dogs, and is used to control roundworms and hookworms in cats.

As with all heartworm medications, Stronghold is a preventative measure and does not treat existing heartworm. Please ensure to have your pet tested for heartworm first.


  • Broad spectrum treatment controls multiple parasites
  • Topical application ensures the product will not be refused
  • Waterproof formula is great for active pets
  • Safe for breeding, pregnant or nursing pets

    레볼루션 대용
    할인 먹어서 81달라 추적등기 7달라해서 88달라에 구입함 가격만 보면 작년 동물약국에서 구입하던 레볼루션 가격인데 물가가 올라서 체감은 비슷함 열흘만에 왔고 바로 고양이 발라줌. 독한 냄새 똑같고 같은 약인 듯 처방전 필요없는 동물약을 왜 동물병원이 독점해야 하는지 이해를 못 하겠다.
    병원에서 애드보킷으로 접종했었습니다 펫버킷을 알게되어 직접 구입해서 사용했는데 아이들 전부 별탈없이 건강하요^^ 애드보킷이 약이 독하다고 해서 스트롱홀드로 구입했는데 부작용도 없고 좋아요!!
    애드버킷보다 사용하기가 편해요
    잘 받았어요
    한 5일 못 돼서 받은 것 같아요 저렴하게 구매해서 좋습니다
    Great Product
    Perfect for my kitten whose under 2.5 kg. I ordered the 6 pack. No fleas.
