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.
After receiving the first injection, your dog must remain as quiet and inactive as possible for the next 8 weeks (confine to crate or small room). This may seem unfair, but the alternatives are worse and potentially life-threatening.
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.
How long after heartworm treatment can a dog be active? According to Dr. Marteney, your dog will have to wait about six months after his diagnosis before he can get back to all his favorite activities.
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.
Try a game of stationary catch or use a clicker to train him to follow quiet commands while he's in his crate. Keeping your treated dog calm and quiet is one of the most important responsibilities a pet owner has during heartworm treatment.
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.
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.
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.
Your dog must be kept as quiet as possible.
Walking outside to use the restroom or to sit outside with you to enjoy the weather is ok, but no walks (short or long) for exercise. Be advised that the severity of heartworm disease is directly related to the activity level of the dog.
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.
The injections are given within the muscle and can indeed be uncomfortable, but the inflammation that develops within the days following creates the most discomfort. Restlessness, panting, trembling and reduced appetite can all be signs that the dog is uncomfortable.
The medicine in the treatment (Immiticide) can cause a lot of inflammation at the injection site. This can occur no matter how smoothly things go and how little it seems to bother the dog at the time. This can range from being absolutely undetectable to a dog that is crying constantly with pain.
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 preventatives can cause serious side effects in some dogs, including depression, lethargy, vomiting, anorexia, diarrhea, dilation of the pupil, loss of balance, staggering, convulsions, and hy-persalivation.
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."
Approximately 6 months after treatment is completed, your veterinarian will perform a heartworm test to confirm that all heartworms have been eliminated. To avoid the possibility of your dog contracting heartworm disease again, you will want to administer heartworm prevention year-round for the rest of his life.
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.
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.
According to the American Heartworm Society, I=if you are doing a fast-kill protocol, your heartworm-positive dog should not exercise for a minimum of 4 months, and the recommendations seem to be shifting to even 6 months – from diagnosis to 8 weeks after treatment is completed.
The treatment for heartworm disease takes at least 60 days to complete and consists of a series of drug injections that kills the worms.
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 melarsomine injections are pretty painful for dogs, which means you'll need to give your dog even more medication. “The injection is painful,” Dr. Marteney said.
Heartworm disease is not contagious, meaning that a dog cannot catch the disease from being near an infected dog.
Your heartworm positive dog, after receiving melarsomine treatment will be instructed to remain caged, crated or penned for the duration of this phase of treatment except when they need to go outside to potty.
