April Is Heartworm Awareness Month
Are your pets protected against this deadly yet easily preventable disease ?
Across the country — from east to west and north to south — balmy winter weather is creating ideal conditions for an early crop of mosquitoes. And for pets, mosquitoes are more than a nuisance; these pesky little blood-sucking beasts are responsible for transmitting deadly heartworm disease.
A nationwide incidence survey conducted by the American Heartworm Society in 2010 confirmed that heartworm incidence and its risk factors are impossible to predict. Multiple variables, from microclimates to the presence of wildlife carriers, cause rates of infection to vary dramatically, even within communities. Because these factors are so variable, we never know when mosquitoes will emerge in the spring or how late into fall they’ll hang around.
Heartworm is a serious disease that threatens the lives of infected dogs and cats. Fortunately, heartworm prevention is relatively inexpensive and easy to administer. And because neither you nor your veterinarian can predict when or where your pet might be exposed, the American Heartworm Society recommends that you Think 12: (1) get your pet tested every 12 months for heartworm and (2) give your pet heartworm preventive 12 months a year.
Think 12 and you won’t need a crystal ball!

April is Heartworm Awareness Month
Heartworm disease is a serious and potentially fatal condition caused by parasitic worms living in the arteries of the lungs and occasionally in the right side of the heart of dogs, cats and other species of mammals, including wolves, foxes, ferrets, sea lions and (in rare instances) humans. Heartworms are classified as nematodes (roundworms) and are filarids, one of many species of roundworms. Dogs and cats of any age or breed are susceptible to infection. Learn more...
Where is Heartworm Disease?
Heartworm disease has been reported in all 50 states. The map below shows particularly endemic areas based on the number of cases reported by clinics.
History
The first published description of heartworm in dogs in the United States appeared more than 100 years ago in an issue of "The Western Journal of Medicine and Surgery."1 Heartworm in cats was first described in the early 1920's.2, 3
Since then, naturally acquired heartworm infection in cats and dogs is identified as a worldwide clinical problem. Despite improved diagnostic methods, effective preventives and increasing awareness among veterinary professionals and pet owners, cases of heartworm infection continue to appear in pets around the world.

How Heartworm Happens: The Life Cycle
First, adult female heartworms release their young, called microfilariae, into an animal's bloodstream. Then, mosquitoes become infected withmicrofilariae while taking blood meal from the infected animal. During the next 10 to 14 days, the microfilariae mature to the infective larval stage within the mosquito. After that, the mosquito bites another dog, cat or other susceptible animal, and the infective larvae enter through the bite wound. It then takes a little over 6 months for the infective larvae to mature into adult worms. In dogs, the worms may live for up to 7 years. Microfilariaecannot mature into adult heartworms without first passing through a mosquito.
What Are the Signs of Heartworm Disease?
For both dogs and cats, clinical signs of heartworm disease may not be recognized in the early stages, as the number of heartworms in an animal tends to accumulate gradually over a period of months and sometimes years and after repeated mosquito bites.
Recently infected dogs may exhibit no signs of the disease, while heavily infected dogs may eventually show clinical signs, including a mild, persistent cough, reluctance to move or exercise, fatigue after only moderate exercise, reduced appetite and weight loss.
Cats may exhibit clinical signs that are very non-specific, mimicking many other feline diseases. Chronic clinical signs include vomiting, gagging, difficulty or rapid breathing, lethargy and weight loss. Signs associated with the first stage of heartworm disease, when the heartworms enter a blood vessel and are carried to the pulmonary arteries, are often mistaken for feline asthma or allergic bronchitis, when in fact they are actually due to a syndrome newly defined as Heartworm Associated Respiratory Disease (HARD).
How Do You Detect Heartworm Disease?
Heartworm infection in apparently healthy animals is usually detected with blood tests for a heartworm substance called an "antigen" ormicrofilariae, although neither test is consistently positive until about seven months after infection has occurred.
Heartworm infection may also occasionally be detected through ultrasound and/or x-ray images of the heart and lungs, although these tests are usually used in animals already known to be infected.
Prevention
Because heartworm disease is preventable, the AHS recommends that pet owners take steps now to talk to their veterinarian about how to best protect their pets from this dangerous disease. Heartworm prevention is safe, easy and inexpensive. While treatment for heartworm disease in dogs is possible, it is a complicated and expensive process, taking weeks for infected animals to recover. There is no effective treatment for heartworm disease in cats, so it is imperative that disease prevention measures be taken for cats.
There are a variety of options for preventing heartworm infection in both dogs and cats, including daily and monthly tablets and chewables, monthly topicals and a six-month injectable product available only for dogs. 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.
It is your responsibility to faithfully maintain the prevention program you have selected in consultation with your veterinarian.
Treatment
 Heartworms in the heart of a dog |
Usually, all but the most advanced cases of heartworm disease can be successfully treated in dogs. Currently, there are no products in the United States approved for the treatment of heartworm infection in cats. Cats have proven to be more resistant hosts to heartworm than dogs, and often appear to be able to rid themselves of infection spontaneously. Unfortunately, many cats tend to react severely to the dead worms as they are being cleared by the body, and this can result in a shock reaction, a life-threatening situation. Veterinarians will often attempt to treat an infected cat with supportive therapy measures to minimize this reaction; however it is always best to prevent the disease.
 Heartworms in the Pulmonary Artery of a dog |
Adult heartworms in dogs are killed using a drug called an adulticide that is injected into the muscle through a series of treatments. Treatment may be administered on an outpatient basis, but hospitalization is usually recommended. When the dog is sent home, exercise should be limited to leash walking for the duration of the recovery period, which can last from one to two months. This decreases the risk of partial or complete blockage of blood flow through the lungs by dead worms.
Re-infection during treatment is prevented by administration of a heartworm preventive. These preventives may also eliminate microfilariae if they are present. Dogs in heart failure and those with caval syndromerequire special attention.

Sugar-Free Gums & Candies Can Be Dangerous For Your Dog !
Xylitol is a sugar substitute ingredient commonly found in many sugar-free gums and candies. It has also recently been added to some toothpastes. If your pet is like mine, they may like to eat any or all of these things and are therefore at risk of ingesting toxic xylitol.
Xylitol is not harmful to people but dogs metabolize it rapidly in their blood, causing their body to release insulin and quickly lower blood sugar. Signs of low blood sugar that might be noticed after ingestion are weakness, staggering, seizures, and coma. Xylitol can also lead to liver damage and death if a high enough dose is ingested. Other signs of ingestion/toxicity may include vomiting and diarrhea and these may be the first signs that are noticed.
**A TOXIC DOSE OF XYLITOL CAN BE AS LITTLE AS 1-2 PIECES OF CHEWING GUM FOR A 20 POUND DOG!!**
If you suspect your pet has ingested any amount of food or oral hygiene product containing xylitol please contact your veterinarian immediately. If the ingestion has occurred recently (within 1-2 hours) your vet may induce vomiting to eliminate as much of the xylitol from the body as possible.
Although there is not a specific antidote, blood tests can be performed to see if any changes to blood sugar or liver enzymes is occurring. Symptomatic treatment is started based on the severity of signs and may include: fluids with or without dextrose (sugar) added, anti-vomiting and anti-diarrhea medication, antibiotics, and liver protectant medication.
Remember to keep all products containing xylitol out of your pet's reach because most of them taste good to pets.
