The main difference is that the Iverhart Max will control an additional intestinal parasite (tapeworms). Otherwise the medications will both protect against heartworms, roundworms, hookworms and are generally well tolerated. The Max product does contain an additional ingredient (to kill the tapeworms). Again, this ingredient is generally well tolerated but watch Benji after giving him the medication for any signs of GI upset. Thank you for your questions.

Heartgard plus is a prescription only medication, so you need to get a script from Akita's vet in order to get it. You can call and ask them to write a script for it if she's been seen by the vet within in the last year. Otherwise, you will have to make an appointment.

Tri-Heart is generic Heartgard and is just as effective. I am not sure why your vet won't prescribe it for you. You cannot buy any heartworm prevention over the counter so you will need a prescription. I suggest you bring your dog to one of the VETCO vaccine clinics at your local Petco stores (see schedule below). Bring proof of his last negative heartworm test and they can give you a prescription for the Tri-Heart. There is no charge for the exam. Just the cost of the medication. Hope this helps!

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. The general dose of the liquid pyrantal is 1 ml per 10 pounds of body weight. You can very safely give 1.5 ml to the 15 pound dog & 2.0 ml to the 20 pound dog every month with the Iverheart & this is essentially the Iverheart Plus. Take care.

If you have proof that the dogs have a current negative heartworm test (current means a test within the last year) then you can get the product at any one of our VETCO vaccination clinics. If you do not have proof of a negative heartworm test, you can get the test done at the clinic and then you can buy the Interceptor (or any type of heartworm prevention).
