Win A Lifetime Supply Of Heartworm Medicine For Your Dog

heartworm medicine

Can you imagine a foot-long worm living in your heart?  It sounds like something out of a science fiction movie, but unfortunately, these creatures are real and prominent in Oklahoma.  Heartworms pose a serious and often fatal threat to dogs living all over the United States.  The cost of treatment for heartworms is fifteen times more expensive than heartworm medicine.

How does heartworm medicine work?

To understand how heartworm medicine works, it’s important to understand the life cycle.  Heartworms are transmitted from one infected dog to another by a mosquito.  The immature heartworm slowly matures and migrates through your dog’s body until it reaches the heart six months later.

Heartworm medicine works by killing the immature heartworm at a specific point in its lifecycle.  Dr. Coffin recommends heartworm medication every 30 days all year long.  Missing one single dose can allow the immature heartworm to advance and continue to an adult worm.  Heartworm medicine is not effective at killing adult heartworms.

Heartworm medication is a prescription medication that must be purchased from your veterinarian.  Before giving your dog heartworm prevention, it is important to test your dog for adult heartworms.  Certain heartworm medicine can cause a harmful and even fatal reaction if your dog has adult heartworms.  It is safe to start puppies younger than six months of age on heartworm prevention without testing them because it takes six months for a heartworm to reach the heart.  In fact, Dr. Anna Coffin recommends starting puppies on heartworm prevention at eight weeks of age.
