Although there are some risks associated with this medication's use, most adult worms die quickly and can be eliminated within 1 to 3 months. Cage rest and drastically restricted exercise during this period can decrease the chances of complications from treatment.
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.
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 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.
Treatment Requires a Vet's Help
Once a positive test is confirmed, our veterinarians (in alignment with the American Heartworm Society) recommend treating adult heartworm infections with 3 treatments (injections) of a drug called melarsomine.
Usually, your dog can slowly resume activity at this time. Remember that every dog living in an area where heartworms exist needs to receive regular heartworm preventative (usually once monthly, given orally at home).
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."
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.
Is heartworm painful? - Animal Hospital of Statesville. It's not painful, per se, but they feel sick, uncomfortable, and they're likely having difficulty breathing. They're not perfusing very well, so they don't feel well.
Dogs that have a high number of heartworms often develop symptoms such as pronounced and persistent coughing, difficulty breathing, and exercise intolerance. In more severe cases, dogs may also experience fainting or collapse, pale mucous membranes, weakness, elevated heart rate (tachycardia) and severe lethargy.
Some dogs live with heartworms for a long time with little to no outside indicators of infection, especially if they don't have many heartworms. That said, heartworms have a lifespan of five to seven years, so unfortunately they have plenty of time to wreak havoc on your dog's system.
There should be no physical activity for 6 weeks or until cleared by the veterinarian. No play, no running. Active dogs that have a hard time resting after treatment, may be prescribed calming meds during recovery. The recovery period is a great time to train the brain.
n A new infection is possible if the monthly preventive was dosed incorrectly, or a dose was missed or accidently not ingested by the dog. Also, the monthly prevention should be started three weeks following the last treatment injection; if there was a delay a new infection is more likely.
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.
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.
Lethargy and reluctance to exercise are common signs described in dogs with advanced heartworm disease. If your pet loses interest in going for walks or is fatigued after activity, it may be a sign of heartworm disease. Some dogs have a decreased appetite and, as a result, lose weight.
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.
They can be controlled naturally with citrus oils, cedar oils, and diatomaceous earth. Dogs needing conventional treatment may benefit from herbs such as milk thistle and homeopathics such as berberis; these minimize toxicity from the medications and dying heartworms.
Heartworms can also cause nosebleeds, pneumonia, high blood pressure, seizures, blindness, and excessive sleeping.
This stage is life-threatening and requires quick surgical removal of the heartworms. However, surgery is risky and even with surgery, most dogs in this stage die. Not all dogs with heartworm disease develop into stage 4.
Not every aspiring pet owner is equipped to provide the extra care a special-needs pet requires; however, with proper treatment, heartworm-positive pets can be excellent candidates for adoption.
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.
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.
“No running, jumping, playing or high-impact exercise as these activities may cause the worms to break loose and cause significant harm to the pet being treated.”
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.
