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.
Allowing vigorous activity at any time in these 8 weeks can cause the weakened heartworms to shatter, causing a clot of worm fragments that blocks off blood flow to the lungs, brain, or other organs (“shaking the tree” phenomenon). This causes a stroke or sudden death.
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.
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.
Once treated, the heartworms die slowly and begin to dissolve, taking several weeks. Three to four weeks later, your dog will begin phase two to get rid of the baby heartworms. Following that, continued checkups and testing continues, and your canine pal will be placed on heartworm preventative medication.
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."
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.
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.
The treatment for heartworm disease takes at least 60 days to complete and consists of a series of drug injections that kills the worms.
While 100% of adult worms might be dead at the 6-month point, residual heartworm antigen in circulation is detectable for a time and could lead to an invalid test result. Waiting an additional 3 months allows time for the antigen to be cleared from the dog.
What health criteria must my dog meet? We require all dogs who stay here to be current on the usual core vaccinations, as well as receiving a vaccination for Bordatella (kennel cough). Your dog must also be protected against heartworm and fleas, with no signs of parasite issues in his fecal sample.
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.
Step 7: Home Care During Heartworm Treatment
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.
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.
Keeping Your Heartworm Positive Dog Happy
Give several; short leash walks during the off-temperature times of the day. These are SHORT walks, 10 minutes max at a leisurely pace.
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.
The dog's immune system must break down the dead worms, an elimination process which is very effective but does take some time. While that immune process is taking place, fragments of dead heartworms are circulating in the blood stream.
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.
The Immiticide is administered by deep intramuscular injections in the lumbar muscles. These injections can cause pain and soreness to spread throughout the lower back causing temporary difficulty getting up because of the muscle soreness. Some dogs experience nausea and are lethargic.
Final Visit & Test – 8 months after Check Up:
A final examination is performed by a veterinarian, along with a test to see if the results come back confirming that your dog is now (hopefully) heartworm negative.
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.
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.
What to expect after heartworm treatment. 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.
Heartworm treatment is a process carried out through 4-6 months. During heartworm treatment the patient must stay confined while the heartworms are dying off to prevent embolisms and other health risks.
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.
