Importance of Heartworm and Flea Prevention

July 11, 2025

Heartworm and flea prevention are crucial aspects of maintaining the health and well-being of both dogs and cats. Heartworm disease, caused by parasitic worms transmitted through mosquito bites, can lead to severe lung disease, heart failure, and even death if left untreated. Treatment of heartworm infection in dogs is very costly and some dogs do not survive it. There are no good treatment options for cats with heartworm infection. Annual testing for heartworm infection is important in dogs and cats as some preventions can cause severe side effects if given to pets with an active heartworm infection. Fleas are common external parasites that can cause intense itching, allergic reactions, and transmit diseases such as tapeworms. Both heartworm and flea infestations can be prevented through proper medication and regular treatments.

 

For heartworm prevention, there are a variety of options available for pets, including oral medications, topical treatments, and injectable solutions. These treatments work by killing the heartworm larvae before they mature into adult worms. The most effective prevention plans are typically administered monthly, starting when pets are as young as eight weeks old.

 

Flea prevention involves a combination of treatments designed to kill adult fleas and prevent their eggs and larvae from developing into adults. Monthly topical treatments, oral medications, and collars are common methods for flea control. In Florida, oral flea prevention is the most effective at preventing flea infestations. Prevention should be given year-round, as fleas can survive in a variety of climates and indoors, even during winter months.
