IMPORTANT: See your veterinarian routinely. In most cases, a heartworm test should be performed and confirmed negative by a veterinarian before allowing your dog to take heartworm preventive medication.

Heart-healthy tips:

  • Read the entire label and directions before giving PetTrust™ Plus (ivermectin/pyrantel) to your dog.
  • If your dog does not willingly accept PetTrust Plus, try adding it to a small amount of your dog’s food.
  • Always mark the date you give PetTrust Plus in your calendar and set a reminder for the next dose.

IMPORTANT INFORMATION: Dogs should be tested for heartworms prior to use. In a small percentage of treated dogs, digestive and neurological side effects may occur. Please see full product insert for more information.
