- There are a variety of options for preventing heartworm infection in both dogs and cats, including daily and monthly tablets and chewables and monthly topicals. All of these methods are extremely effective, and when administered properly on a timely schedule, heartworm infection can be completely prevented. These medications interrupt heartworm development before adult worms reach the lungs and cause disease.
- In cats, there are three products currently approved to prevent heartworm infection, two oral medications and one topical medication.
- Pet owners should discuss the proper product selection for their pet and dose timing with their veterinarian.
