How to Use Ivermectin on Dogs

Ivermectin is a drug used to prevent parasitic infections, such as heartworm disease, in dogs. Heartworm disease affects a dog's heart and lungs, causing respiratory or congestive heart failure, leading to death. A prescription drug, Ivermectin is only available through your veterinarian. Ivermectin is the main ingredient in Ivomec Wormer, a cheaper alternative to Heartgard. When administering Ivomec Wormer, pet owners must measure the correct dosage, ensuring little chance of overdose. Aside from dogs, Ivomec Wormer is also used to treat parasitic infections in livestock such as cattle and sheep.
