Easy to administer and tolerated. My 12 yr old Beagle takes them once a month. When I adopted her she was heartworm positive. She went through treatment and has been heartworm negative for almost 2 years now, so it's very important that she remains on a once a month schedule. Chewy makes it easy to order they contact the Vet if you want. We love Chewy!

Happy with the product and I am very happy with the delivery time!

My dog has used this for years without side effects! It does the job very well!

just want to thank you all for your help with getting Gunny his heartworm pills, youwent all out in your efforts and it is truly appreciated, thank you all

Ordered this brand to save a few dollars from the name brand Heartguard. While these are just as effective in protecting against heartworms they are difficult to dispense. These are small hard tablets that are supposed to be chewed by your dog, however, they are always swallowed whole by my pet. A larger chewie pill would encourage chewing better than this tablet.

...as usual! Sent vet script to them....in a matter of days tablets arrived! Does Chewy do anything average?? Nope!

I'm so glad my mom gives me Iverhart Plus. It keeps me from getting heartworms. My mom must really love me, because she gives me one every month so I can stay healthy. It's good for all dogs.

These were Vet prescribed and found them less expensive on Chewy. Sahara has been on this guard since a pup. Once a month chewable and done.

The pills are easy to feed. Small enough to hide. No Problems with giving it to all 4 dogs.

So fabulous to not have to go back to vet for rx. Thank you chewy :)
