• Dogs with heartworm disease can be successfully treated and go on to live normal lives. However, treatment must be initiated as soon as possible to minimize permanent damage to the dog’s heart and arteries. • A dog with heartworm disease cannot directly infect another pet.
Heartworm disease is not contagious, meaning that a dog cannot catch the disease from being near an infected dog. Heartworm disease is only spread through the bite of a mosquito. Inside a dog, a heartworm's lifespan is 5 to 7 years.
Since the mosquito is needed to carry the microfilariae, heartworm disease is not contagious from one dog to another dog. People also cannot get heartworms from dogs. Dogs and humans can only get heartworms from infected mosquitos.
Myth: Heartworm disease is contagious for pets.
Truth: You should be concerned if we diagnose one of your pets with heartworm disease, but you do not need to quarantine your infected pet. Heartworms must go through a mosquito to develop into adults, so heartworm-positive pets are safe to be around.
With minor variations, treatment of heartworm disease typically takes 2-5 months to complete. The most important thing you can do during the treatment is to restrict your dog's physical activity to a bare minimum of short leash walks for bodily functions (urinating, defecating) only.
A pivotal factor in reducing the risk of thromboembolic complications is to restrict exercise during the critical month following treatment. Dogs that have undergone heartworm treatment should be kept on strict rest. If the dog is calm while indoors, he/she can be allowed loose in the house to rest.
The lifespan of a dog in this condition is most likely limited to a few weeks or a few months. Your vet will guide you on the best course of action for treating your dog depending on the severity of their infection. Dogs can live for at least six to seven months after becoming infected with heartworms.
Your dog won't be able to be active after his heartworm treatment for at least a few months. “The dead heartworms take some time to be broken down by the dog's immune system,” Dr. Marteney said. If the dead worms are still intact, they can cause major issues if your dog's heart rate becomes elevated.
Prognosis: heartworm treatment success rates
With the three-dose adulticide protocol described above, in conjunction with doxycycline and macrocyclic lactones as recommended by the American Heartworm Society, 98% of dogs will be cleared of heartworm infection.
Ultimately, heartworm treatment involves giving your dog what's known as an “adulticide” medication that eliminates the adult worms living in the blood vessels, lungs and heart.
Dogs who cough often may cause themselves to vomit as a result of their extensive coughing. Some dogs may feel nauseated from their heartworms as well, and may vomit often just because they feel so sick with the disease.
Dogs with heartworm disease can live high-quality lives as long as they are given appropriate care. After completing treatment and following your veterinarian's recommenda- tions on heartworm disease testing and prevention, the chances of any long-term effects are very low.
The trauma caused by even a small number of heartworms can lead to rapid and often permanent change within the pulmonary arteries.
How soon after infection will a dog show signs of heartworm? - Haywood Animal Hospital. It can take several months to start seeing actual signs, as it takes anywhere from six to eight months for the larva to reach the adult stage. It can even take up to two years to see any signs.
Since the treatment involves killing the heartworms while they're still in your dog's body, it's crucial to make sure he's inactive during and after treatment — meaning no running, jumping and playing.
From the first injection until six to eight weeks following the last injection, it will be absolutely essential to keep your dog quiet. That means strictly restricting all exercise and activity that would elevate your dog's heart rate or increase his blood pressure.
Strict rest is imperative for 6-8 weeks. This means that your pet can be leashed walked outside to urinate and defecated, but must come back inside to rest. Do not allow your pet to run, jump, climb stairs, or play rough with other dogs or children.
Heartworms can also cause nosebleeds, pneumonia, high blood pressure, seizures, blindness, and excessive sleeping. When heartworms reach places other than the heart and lungs, like the brain and eyes, dogs will experience seizures and blindness.
Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss. As heartworm disease progresses, pets may develop heart failure and the appearance of a swollen belly due to excess fluid in the abdomen.
In severely affected dogs, you may see a swollen abdomen due to fluid buildup because the heart cannot effectively circulate blood, or notice a cough, or other signs such as respiratory distress. Heartworm disease in dogs is known as a silent killer, because it can take months before your dog shows symptoms.
Timing of doxycycline administration (before or after transport) can be tailored to the situation. Meanwhile, transporting dogs that are exhibiting clinical signs of heartworm infection should be avoided.
Heartworms are never passed from an infected animal directly to another animal through contact or shared food and water bowls, nor does an animal get them from drinking bad water. It always comes down to a mosquito bite.
Symptoms of heartworm disease can include:
Coughing or difficulty breathing. Weight loss. Sudden collapse. Increased thirst (due to kidney disease)
