There are many different options out there for heartworm preventatives.
- Advantage Multi is topical solution that is applied directly to the skin once a month. The important thing with this is that your pet cannot have a bath (or go swimming) for 2 days prior and after application. This protects your pet against heartworms and fleas. It also protects against Intestinal Parasites including hookworms, roundworms, and whipworms. This is also the product that is used for your feline friends (in their own specialized formula) to protect against heartworm disease, fleas, and the other parasites listed above.
- Interceptor is a flavored chewable oral tablet given once a month. This prevents against heartworms, hookworms, roundworms, and whipworms.
- Trifexis is a flavored chewable oral tablet given once a month with a meal. This prevents against heartworms, fleas, hookworms, roundworms, and whipworms. One of the benefits of Trifexis is that it is soy-based, so is compatible with dogs that have food allergies.
