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.
While heartworm disease can be life-threatening, there are effective treatment options for established heartworm infections, and strict rest during the treatment period is critical to recovery.
Many dogs treated for heartworm have close to a normal life expectancy, depending on how quickly the disease was found. Without treatment, heartworm disease will shorten a dog's natural life expectancy.
Additionally, even though melarsomine is highly effective, a single course of treatment may not completely clear all dogs of infection (the American Heartworm Society protocol calls for three separate injections of melarsomine.
Even though heartworm preventives are nearly 100% effective in precluding infection when administered according to instructions on the label, animals on heartworm prevention occasionally test positive.
(CN) – A federal class action claims the makers of a popular heartworm medicine have ignored 7 years of warnings from the FDA and jeopardized the lives of thousands of dogs by continuing to misrepresent the drug as “100 percent effective.” The class claims Merial misrepresented its HeartGard Plus medication because ...
It is also imperative to have your pet tested yearly for heartworms while on preventative. Heartworm preventatives are highly effective, but dogs can still become infected. If you miss just one dose of your monthly medication – or give it late – it can leave your dog unprotected.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
In the newly infected dog, it takes about 6 to 7 months for the infective larvae to mature into adult heartworms. The adult heartworms mate and the females release their offspring into the dog's bloodstream, completing the lifecycle. See a graphic of the heartworm lifecycle in dogs.
The "10 10 10 rule" for dogs refers to two main concepts: a potty training method for puppies (10 mins outside, 10 ft space, 10 mins supervision/reward) and the 80/10/10 guideline for raw feeding (80% muscle meat, 10% bone, 10% organ), both offering structure for training or diet. Another interpretation is the 10% rule for treats, limiting them to 10% of daily calories to maintain a balanced diet, ensuring most nutrition comes from complete dog food.
If your dog loves to play throw the ball, don't do that for the couple months they're needing rest. If there are things that get your dog real excited around the house, jumping up and down on the couch, running around when the doorbell rings, try and limit those things.
It takes several months for the body to absorb the decomposed heartworms. Most problems after treatment occur due to these decomposing fragments. To reduce the risk, your dog should avoid exercise and be kept calm for the first month after treatment.
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 first 7 -10 days after heartworm treatment are the most dangerous. But your dog is not out of the woods for several weeks more. These side effects are happening because the dead worms are breaking up and being carried into the lungs where they cause severe inflammation. With time, the body absorbs them.
Moxidectin-doxycycline (moxi-doxy) provides a viable alternative to no treatment at all, in cases where arsenical treatment is not possible. Based on current evidence, the most effective non-arsenical treatment regimen is doxycycline 10 mg/kg PO q 12 or 24 h for 28 days, combined with topical moxidectin at label dose.
If the blood test comes back positive, then the following tests will also be performed to determine the stage and severity of the disease in order to determine the most appropriate treatment plan: A urinalysis, or the testing of a dog's urine. An antigen test determines the presence of adult female heartworms.
However, Heartgard Plus Chewables cannot prevent the development of the adult stage. Use with caution for collies and other herding dog breeds. These breeds have been known to have adverse reactions to ivermectin at elevated dose levels.
Yes. While treatment includes giving several different medications over a period of weeks and months, dogs infected with heartworms can be successfully treated. It's critical that dogs undergoing treatment be kept quiet and calm from the time of diagnosis until several months after the treatment has ended.
The most commonly surrendered dog type is the "pit bull type" (including mixes), often due to negative stereotypes, breed-specific legislation, and high energy levels, followed by other popular breeds like German Shepherds, Huskies, and Labrador Retrievers that may not fit owner lifestyles. Breeds like Staffordshire Bull Terriers (especially mixes) also top surrender lists in some regions like Australia.
The seven second rule. Put the back of your hand on the pavement. If you cannot hold it for seven seconds, it is too hot to walk for your dogs. This rule also applies to dogs riding in the bed of a pickup truck.
Place the back of your hand on the pavement. If you can't keep it there for five seconds, it's too hot to walk your dog. If you didn't know about this rule, chances are your friends don't, either.
It is also important to remember that Heartgard Plus only prevents heartworm disease and does not treat it, so it is important to have your dog tested for heartworms on a regular basis, as recommended by your veterinarian.
Recognizing Symptoms Quickly
Heartworm disease can progress slowly, sometimes taking one to two years to reach advanced stages. The initial larvae reach adulthood in approximately seven months, and then they multiply. The length of time makes recognizing symptoms difficult because the signs may seem gradual.
After diagnosis, the first order of business is to limit your pet's physical activity—and that means more than just skipping the dog park. Even moderate exercise increases the risk of serious complications as heartworms begin to die off and break apart during treatment.
