Heartgard Chewable Dogs
- Highly effective in preventing heartworms

How it works: Heartgard prevents heartworm disease by eliminating the tissue stage of heartworm larvae for a month after infection.
It is important that you give your pet this preventative every month. If you miss more than two monthly doses, we recommend calling your vet before continuing the medication. Also, note that side effects are rare at the recommended heartworm prevention dose. Higher doses in dogs may cause tremors, dilated pupils, loss of body weight, and death. Side effects in cats include agitation, loss of appetite, staggering, dilated pupils, tremors, blindness and disorientation.
