Frequently Asked Questions

Q1: What parasites does Iverhart Max Chew for Medium Dogs protect against?

Ans: Iverhart Max Chew helps prevent heartworm disease by eliminating tissue stage larvae and treats and controls common intestinal worms, including roundworms, hookworms, and tapeworms in dogs. It provides broad-spectrum parasite protection when administered monthly according to veterinary guidance.

Q2: How often should I give Iverhart Max to my dog?

Ans: The chew should be administered once every month to maintain continuous protection against heartworm infection and intestinal parasites. Consistent monthly dosing is important because delays longer than thirty days may reduce effectiveness against developing heartworm larvae.

Q3: Do dogs need a heartworm test before starting Iverhart Max?

Ans: Yes, dogs should be tested for existing heartworm infection before starting treatment and again six months after beginning a prevention program. The medication does not eliminate adult heartworms, so infected dogs require appropriate treatment before preventive use.

Q4: Can Iverhart Max be given with food?

Ans: The chew can be offered by hand or mixed with a small amount of dog food. Pet owners should make sure the dog eats the entire dose and watch for a short time after giving it to confirm the chew was not rejected.

Q5: Is Iverhart Max safe for all dog breeds?

Ans: When used at the recommended dose, the product is considered safe for dogs, including Collies. However, certain breeds may be more sensitive to ivermectin at higher doses, so veterinary supervision and correct dosing based on body weight are essential.
