Start by seeing your veterinarian

It’s important to talk to your veterinarian when determining how to protect your dog from parasites. Your visit might include:

  • Administering a test to ensure your dog is free from heartworm infection before beginning a heartworm disease preventative
  • Taking stool samples and running tests
  • Assessing your dog’s lifestyle to determine which worms are of concern and which worm protection products are best suited for your dog
  • Discussing the need for year-round parasite protection
