                           About Heartworm Disease 

Heartworm disease is a serious illness that can rob your dog of its health and even its life.

Heartworm larvae are transmitted by infected mosquitoes that bite the dog and deposit heartworm larvae on the dog's skin. The larvae migrate through the tissue and into the bloodstream of the dog where they continue developing. By the time clinical signs of heartworm disease appear, the disease can already be in its advanced stages.

Heartworms spend their adult lives in the right side of the heart and the large blood vessels that connect the heart to the lungs. The adult worms block the heart and major blood vessels leading from the heart to the lungs, liver, and kidneys and can grow up to 12 inches long.

Heartworm disease has been reported in all 50 U.S. states.

Your dog deserves protection against heartworms – and it's easy to do.

Heartworm disease can affect dogs anywhere. The disease has spread to every corner of the U.S. and hundreds of thousands of cases are reported every year1. Heartworm disease can be prevented by administering an effective heartworm preventive year-round. Protecting your dog against heartworms and heartworm disease can be convenient, simple, and affordable.

How can heartworm disease be prevented?

Heartworm disease can be prevented by keeping your dog on monthly form of Heartworm Prevention such as HeartGuard, IverHeart Max, Interceptor, etc.... It is important to keep your pet on the monthly Heartworm prevention each month and to have a yearly Heartworm test.

 

Why shouldn't I wait and see if my dog develops heartworm disease? Can't my veterinarian just treat it?

It's important to understand that heartworm disease has usually reached an advanced stage by the time your dog shows signs of illness, and it is possible that the dog may never show signs of an infection. Treatment is risky, expensive, and may not be effective. The approved treatment involves the use of a product containing arsenic, your dog will be kept inactive during treatment, and you will have to keep your dog inactive for weeks afterward – and despite these measures, treatment may not be successful.

How do dogs get heartworms?

Heartworms are transmitted from one dog to another by mosquitoes, which pick up tiny immature heartworms, called microfilariae, when they bite an infected dog. Larvae develop and are then transmitted to another dog when that dog is bitten by the infected mosquito.

Where are dogs at risk for heartworm infection?

All dogs are at risk for heartworm disease, no matter where they live – heartworms don't discriminate based on geography. In the past, heartworm disease in the United States was primarily limited to the south and southeast regions. However, it is now found in all 50 states, in Canada, and worldwide, and is spreading to new areas each year1. The American Heartworm Society notes that uncared-for dogs and certain wildlife can be carriers of heartworms. Mosquitoes blown great distances by the wind and the transportation of infected pets to different geographic locations can all contribute to the spread of heartworm disease2.

What are the signs of heartworm infection?

Signs of heartworm disease can be subtle and difficult to detect until its later stages. As the disease progresses, signs begin to appear. Contact your veterinarian immediately if you notice coughing, difficulty breathing, sluggishness and less energy for exercise in your dog. Adult heartworms cause serious harm to your dog's heart, lungs and certain internal organs. Left untreated, heartworm disease can result in loss of consciousness and death.

How are dogs tested for heartworm infection?

The most common method for heartworm testing is for a veterinarian to collect a small blood sample from a dog and evaluate the sample using a specialized test kit that identifies the heartworm antigen. Or, your veterinarian may use other types of tests that detect the presence of microscopic microfilariae, an early stage in the heartworm life cycle.

Can heartworm disease be treated?

Although it is possible to treat heartworm disease if a dog becomes infected, it is difficult, expensive and risky, particularly in dogs that have begun to exhibit clinical signs of infection.

Can my dog “get” heartworm disease directly from an infected dog?

No, the way dogs become infected is via a bite from a mosquito that is carrying heartworm larvae.

Are nursing puppies immune to heartworm disease if the mother is receiving Heartworm Prevention?

No. Puppies that are nursing may become infected. HEARTGARD Plus can be used in puppies as young as six weeks of age – and puppies benefit from the ability of HEARTGARD Plus to treat and control roundworms and hookworms.

What is Interceptor?

Interceptor Flavor Tabs are a palatable once-a-month tablet that prevents heartworm disease, controls adult hookworms, and removes and controls adult roundworms and whipworm infections. Interceptor for cats is the only oral monthly preventative that protects against heartworms and removes adult roundworms and adult hookworms.

Broad spectrum activity

How it works:
Interceptor Flavor Tabs eliminate the tissue stage of heartworm larvae and the adult stage of hookworm, roundworm, and whipworm infestations. The anthelmintic activity (destroying parasitic worms) of the active ingredient milbemycin oxime is believed to be a result of interfering with the invertebrates neurotransmission.

For: Dogs (4 weeks of age or older, and weighing more than 2 pounds)

Benefits:
Comes in palatable flavored tabs

How it works:
Milbemycin oxime eliminates the tissue stage of heartworm larvae and the adult stage of hookworm, roundworm, and whipworm infestations.

Lufenuron prevents most flea eggs from hatching or maturing into adults and thus prevents and controls flea populations by breaking the life cycle
