What is Heartgard Plus chewables?

Heartgard Plus is a beef-flavored chewable tablet which prevents heartworm for dogs. It also treats and controls roundworm and hookworm.

Heartworm can be a silent killer because it will go unnoticed by owners most of the time. Heartworm larvae are transmitted by infected mosquitoes. When the infected mosquito bites, the larvae pass through the tissue into the bloodstream. It’s virtually impossible to stop mosquitos from biting your fur babies, so pet owners need to protect them against heartworm.

    FABULOUS purchase for a needed medication.
    Petbucket has always had great prices and fast shipping. Heartworm and worms that can hurt your dog are something we all can face and Petbucket has made it easy to get the medications needed and at a really good price to me every time I have needed it. I had been gone for a bit as I was getting a new dog and they even reached out to me to make things easier with a new puppy. Thank you Pet Bucket!
    My doggies are crazy in this.
    They love soooooooo much to take this. I wonder what is this taste and almost I tasted it. I ordered 1pack : 12 tablets . And Petbucket sent me 2packs: 6 tablets. It was ok. Just keep in mind that. This texture is enough soft to divide with hands. It took 19 days to arrive in EST USA. 우리 강아지들이 환장하고 좋아합니다. 매우 맛있나 봅니다. 약인지 모르고 간식인줄 알고 허겁지겁 먹네요. 3.5 kg 애기들에겐 크기가 좀 커서 손으로 쪼개 주는데 텍스쳐가 쫄깃한 편이라 잘 쪼개지네요. 12알 1팩 주문했는데 6알 2팩으로 보내줬어요. 참고하세요 미국 동부까지 배송 19일 걸렸네요.
    Very good
