Not all dogs with heartworm disease develop caval syndrome. However, if left untreated, heartworm disease will progress and damage the dog's heart, lungs, liver, and kidneys, eventually causing death.
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.
No one wants to hear that their dog has heartworm, but the good news is that most infected dogs can be successfully treated. The goal is to first stabilize your dog if he is showing signs of disease, then kill all adult and immature worms while keeping the side effects of treatment to a minimum.
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.
Active dogs, dogs heavily infected with heartworms, or those with other health problems often show pronounced clinical signs. Signs of heartworm disease may include a mild persistent cough, reluctance to exercise, fatigue after moderate activity, decreased appetite, and weight loss.
Six months after they bite your dog and inject those larval microfilariae heartworms into your dogs, it takes that six months for them to develop into that adult worm. So generally, it's anywhere from six to 12 months after they've been bitten; you may start noticing signs in your pet.
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 American Animal Hospital Association places the average cost of preventative heartworm treatment for dogs at $5-$15 per month and the cost of treating a dog already diagnosed with heartworm at $400-$1,000. With both prevention and treatment, costs typically increase with the weight of the dog.
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.
Adult heartworms have been known to survive inside a dog's heart for 7 years before they die on their own. Your dog does not spit them up, poop them out, or dissolve them on his own. The adult worms will live a long, productive life inside your dog's heart wreaking havoc on his heart and lungs.
Not all dogs with heartworm disease develop caval syndrome. However, if left untreated, heartworm disease will progress and damage the dog's heart, lungs, liver, and kidneys, eventually causing death.
Heartworm disease is a serious condition that can have lifelong effects on the health of your pet – even when it's successfully treated. The good news is, heartworm disease is preventable, so you can rest easy if you're well informed and on top of your pup-parent game!
All of the damage that the heartworms do while they're inside the body is permanent. Sometimes we can reverse some of the symptoms, but all of the damage will still be present.
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.
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.
Heartworm disease can be painful if the heart is very enlarged or if the migration of the worm suddenly happens and causes some issues in the vessels.
Caution: Get professional help for this treatment. Heartworm disease is dangerous and isn't something to treat by yourself. You can treat your dog at home, but make sure you get help from a holistic vet or herbalist.
If owners can't afford treatment at the time of diagnosis, Dr. Herrin recommended delaying melarsomine therapy but still initiating treatment with both a preventive and doxycycline. This will prevent further infection and remove the dog as a heartworm reservoir.
As heart worm disease advances, your dog could develop heart failure and a swollen belly from the excess fluid in his abdomen. If left untreated, heart worm can be fatal. The sooner the disease is detected, the better the chances the pet will recover.
Although there are fewer mosquitoes in the winter, there is still a risk that your pet could get heartworms if you stop giving heartworm prevention medication during this season. That's one reason veterinarians strongly recommend pets receive heartworm prevention medication year-round.
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.
The trauma caused by even a small number of heartworms can lead to rapid and often permanent change within the pulmonary arteries.
Most of the monthly heartworm medicines have a safety factor of at least 15 days of protection if a dose is missed. This means that if you're just a week or two late, your pet is likely still within that window of protection and would be unlikely to become infected during that time.
