Heartworm Prevention

      Even though we are in Frederick, Maryland, mosquitoes and, therefore, heartworms, are still a concern. Anybody that spends time outdoors, particularly in the summertime, knows how prevalent mosquitoes really are. The best way to avoid a heartworm infestation is with a monthly heartworm preventative. The veterinarians at Kingsbrook Animal Hospital recommend two products: Interceptor and Trifexis. Both are tablets that are given by mouth every 30 days. Interceptor is not only a heartworm preventative, but also helps to protect against three different intestinal parasites: hookworm, whipworms, and roundworms. Interceptor was unavailable for period of time, while the company addressed some quality control issues. It has recently come back on the market, and the team at Kingsbrook Animal Hospital is so excited for its return! Trifexis is similar to Interceptor, with protection against heartworms, hookworms, whipworms, and roundworms, but Trifexis starts killing fleas within 30 minutes, before they are able to lay eggs.
It is important to continue a monthly heartworm preventative all year round, even in the dead of winter. There are several reasons for this.  It is difficult to know when the first mosquito will make its appearance, especially with the weather Maryland is known for! Additionally, if a dog were to contract heartworms during the winter months, and prevention is restarted in the spring, the results can be dangerous. The preventative may kill so many heartworms that it could put the pet’s body into shock and have potentially fatal results.
Year round monthly heartworm prevention is not only important, but also life-saving.
