Complete rest is essential after treatment. This can be a dangerous period so it is absolutely essential that the dog be kept as quiet as possible and is not allowed to exercise for one month following the final injection of heartworm treatment.
Most dogs can be safely leash-walked during the treatment recovery period and providing appropriate chew toys can help relieve some of that stored up physical energy.
Enforced Rest is ESSENTIAL! Positively NO Strenuous Exercise for 8 weeks! The heartworms will die over the next 6 weeks. As they die and are broken down, pieces of them could lodge in other parts of the body's blood vessels, causing unnecessary complications–if your pet's activity is too strenuous.
All physical exertion must be stopped beginning the day of the first injection, 24 hours a day, for the full 8-week period, to reduce the risk of serious (catastrophic) heartworm-related problems.
Dogs with heartworm disease, for example, require exercise restriction before and heartworm treatment, as well as for a short time after treatment. Physical activity increases the likelihood of adult worms causing a pulmonary thromboembolism, which may be fatal. Limiting a dog's physical activity decreases this risk.
But your dog's normal physical activities must be restricted as soon as the diagnosis is confirmed, because physical exertion increases the rate at which the heartworms cause damage in the heart and lungs. The more severe the symptoms, the less activity your dog should have.
Rest for 60 days (ideally in a crate): Rest is the single most important factor to successful heartworm treatment. This means 4 weeks of strict rest for your dog after each melarsomine injection.
Once your dog has finished his heartworm treatment, you should expect him to be bedridden for a while. “Only slow, low-impact walks are allowed for the first five to six months after diagnosis,” Dr. Marteney told The Dodo.
If exercise or excitement cause the treated dog's heart rate to rise, pieces of decomposing worms can be forced into the tiny blood vessels of the lungs, causing further complications. The more pronounced the clinical signs of heartworm disease are, the more restricted any activity or excitement need to be.
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.
There is no reason to allow running, jumping, or other physical activity at any time for 8 weeks after the start of the injectable heartworm adulticide treatment.
There is some risk involved in treating dogs with heartworms, although fatalities are rare. "A new drug is available that does not have as many side effects, allowing successful treatment of more than 95% of dogs with heartworms."
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.
Heartworm positive dogs should not exercise. From the day they are diagnosed and receive their first dose of heartworm preventive until the heartworm treatment is complete, the American Heartworm Society recommends that you restrict a dog's activity.
Twenty-six dogs (52%) experienced minor complications, such as injection site reactions, gastrointestinal signs (vomiting, diarrhea, inappetance), and behavioral changes (lethargy, depression) during or after heartworm treatment.
Once your dog has completed the course of steroids, heartworm preventive and antibiotics, he should be ready to start the actual adult heartworm treatment. The treatment for heartworm disease takes at least 60 days to complete and consists of a series of drug injections that kills the worms.
Circulating heartworm antigen appears in the blood as early as five months post-infection in a small percentage of dogs, but most dogs are not antigen positive until seven months post-infection. Yes, contrary to popular belief, a dog infected six months previously can be negative on an antigen test.
Heartworms can also cause nosebleeds, pneumonia, high blood pressure, seizures, blindness, and excessive sleeping.
Heartworm disease is not contagious, meaning that a dog cannot catch the disease from being near an infected dog.
It is critical that your pet be kept under strict exercise restriction and confinement for 4 weeks after each phase of the heartworm treatment. Life threatening complications may arise if your pet is not confined. Specifically, your dog should not be allowed to run loose, play with other dogs, or go for any long walks.
Heartworm disease causes lasting damage to the heart, lungs and arteries, and can affect the dog's health and quality of life long after the parasites are gone.
n The majority of dogs clear all heartworms with the standard treatment, but treatment is not always 100 percent effective. The label reads 90-99 percent effective; this is due to variation in each individual animal.
The dog may be required to stay at the hospital for 3-4 days. After treatment, the adult worms die and are carried by the blood to the lungs where they lodge in small blood vessels. There they decompose and are absorbed by the body over a period of several months.
Myth #3: If my pet has heartworms, I will see them in her feces. Although many worm types, such as roundworms and tiny hookworms, are shed in your pet's feces, heartworms do not live in the gastrointestinal (GI) tract, and are not found in feces.
