Sadly, national reports indicate that heartworm disease is increasing in the United States. Heartworms are found in dogs in every state. It is estimated that more than a million dogs are affected in the US alone.
The immature worms are injected into the dog by mosquitoes where they mature to occupy the dog’s heart and lungs. Untreated, heartworm disease will lead to congestive heart failure and lung damage. Fortunately, regular year-round administration of preventative medications will keep your dog protected. As always, an ounce of prevention is worth a pound of cure.
If your dog is not currently protected and has not had a heartworm test in the last year, please see your veterinarian.
