The way that heartworm prevention works is by killing a larval stage of the worm. These larvae get into your dog from the bite of an infected mosquito. If you don't give your dog the medication every 30 days, the larvae will grow to a point where the preventive won't be able to kill them anymore.
Most of the monthly heartworm medicines have a safety factor of at least 15 days of protection if a dose is missed. This means that if you're just a week or two late, your pet is likely still within that window of protection and would be unlikely to become infected during that time.
Your dog could become lethargic and lose weight and their appetite. These symptoms are often subtle and hard to detect, so prevention is the best option. Treatment for heartworm disease is not without potential risk, may be difficult, and if left untreated, it is nearly always fatal.
Your dog will be protected from heartworm disease because you will still be within the 45-day grace period in which the preventative is effective. Resume your normal monthly dosing schedule. 2.) More than 2 weeks: Contact your veterinarian because you are likely outside of the grace period.
Any time a dog goes more than six weeks without heartworm prevention the dog is at risk of infection.
Left untreated, heartworms can cause enough lung and heart damage to kill your dog. Some dogs who are fortunate to only have a few heartworms may outlive their parasite. But, it takes five to seven years for heartworms to die naturally, during which time they are continuing to cause damage.
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.
Heartworm disease is a very serious parasitic disease that has the potential to be fatal for your dog if he is not treated quickly. This parasite is a worm that can grow up to a foot long and lives inside the heart, lungs, and associated blood vessels of an infected animal where it will reproduce over and over.
A: Give the dose you missed immediately, then continue giving the medication on the day you've always given it. If the missed dose is more than 2 weeks late, your dog should be tested for heartworm again in six months (click here to learn why).

The monthly heartworm preventative we prescribe only lasts in a dog's or cat's body for one to two days, not 30 days, due to the lifestyle of the heartworm, it is only necessary for the pet to take the heartworm preventative every 30 days.
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."
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. Reactions to the drugs are not uncommon, and there is always some risk involved in treating a dog for heartworms.
Proheart SR12 heartworm prevention yearly injection:
Up to 20kg – $141.00. Up to 35kg – $186.75. Up to 50kg – $232.50. Heartworm test – $67.50.
If the lapse is one month or less, reinstitute the preventive and conduct a heartworm test at the next scheduled visit if the visit occurs more than seven months from the current date.
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.
Use Heartworm Prevention Medication Year-Round
Although there are a fewer number of mosquitoes in the winter, there is still a risk that an animal could contract heartworms if the owner stops giving medication during this season.
Yes, it is recommended in the American Heartworm Society's Guidelines to do so. This should be done under the direct supervision of a veterinarian because dogs with microfilaria (baby worms in the blood that the mosquito picks up when feeding) could possibly have a reaction to the preventive.
Heartworm preventives are highly effective, but not 100 percent effective. If you don't get your dog test, you won't know your dog needs treatment.
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.
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.
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.
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.
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.
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. These symptoms will usually ease over a couple of days.
