heartworm test Q & A
Q: If my dog becomes infected with heartworm disease, will he actually have worms inside his heart?
Yes. Inside a dog’s heart, the worms can grow up to 35 cm long and can cause significant damage to the heart and lungs. Literally hundreds of worms may be found in an infected dog’s heart and the surrounding blood vessels. If left untreated, heartworm disease can result in death.
Q: What are the symptoms of heartworm disease?
No symptoms are apparent until the disease is very advanced. For this reason, regular testing is extremely important in dogs. The symptoms of heartworm disease develop gradually over many months, and resemble those of congestive heart failure. In advanced cases, the dog has difficulty breathing, can tolerate only very light exercise, and loses his or her appetite.
Q: Can heartworm disease be treated?
While treatment is possible, the drug required to kill the adult worms is very toxic, and must be administered under close veterinary supervision. The dog must be restricted to cage rest until all danger from treatment has passed. It is far easier, safer, and less expensive to prevent heartworm disease than it is to treat it.
Q: Why does my dog require a heartworm test?
It is important to confirm that your dog is negative prior to beginning heartworm preventative medication. If your dog is positive and he receives preventative medication, he may experience an adverse reaction as the worms and larvae die. Keep in mind that dogs with heartworm infection do not show symptoms until very late in the stage of disease. Early diagnosis is critical.
