About This Item

Details

For use in animals only. Your furry friend must have a current heartworm test result on file with your veterinarian in order to be prescribed heartworm medication. Please visit your veterinarian to have this test performed annually to protect your four-legged friend. Iverhart Plus Chewable Tablets are prescribed to help protect your pet from heartworm disease, which can cause tiredness, decreased appetite and, eventually, heart failure in dogs. These easy-to-feed tablets may also help control two common intestinal parasites, roundworms and hookworms. Iverhart Plus chewables help provide safe and effective protection each month, and come in a pork liver-flavored chewableso they're easy to give to your dog as a tasty treat.

We directly source prescription medications from manufacturers and wholesale distributors registered with the FDA and licensed by applicable state boards. Guaranteed genuine, and where applicable, backed by the manufacturer.

I bought the 27” size, and my 80lb rescue pit bull is absolutely obsessed. Smaller plush toys, she destroys quickly (which is a healthy, controlled way to satisfy natural destructive instincts!), but with huge toys, she befriends them. This instantly became her favorite. She carries it from room to room, between floors in the house, and tries to take it outside (but it’s too muddy to allow at present). She cuddles it or lays her head on it when she sleeps. It’s a perfect shape to contour to a dog’s body. I ordered a back-up already. Get the croissant!

We like giving Our dog Maizie this medicine. 1. She’ll eat it. She avoids most dog biscuits, for example, yet will take and eat this wo hassle. 2. It seems to work. We’ve seen one flea in 16 months (after a trip to a dog park) and no ticks. 3. The only hassle mail order pharmacies is having to snail mail the script. Chewy sends a prompt note when you order it, w mailing address. They acknowledge receipt of your script, and updates to the delivery. 4. We had an issue with the first attempted delivery, but chewy fixed it right away and mailed a second out. Ty!

The chewy box gets here on time every time. They call my Vet to get the prescription. I don't have to worry with any of that stuff. I take my dog for her annual checkup and shots every year on time so there is never a problem.

Our dogs ate them quickly, so I guess they like them which is very good. They are happy and I’m happy.

With pricing on most everything going through the roof, this product is one that can help you save money as it is much cheaper than more marketed brands yet it still provides the same protections of the more expensive heart worm products.
