Dog Heartworm Prevention: Essential Protection
Heartworm disease is a serious condition, but dog heartworm preventatives provide essential protection against this potentially fatal illness. Available as monthly chewable tablets, topical applications, or injections, these treatments kill heartworm larvae before they mature, preventing infection. Veterinarian-approved heartworm prevention ensures your dog stays safe from this life-threatening parasite.
Frequently Asked Questions about Heartworm Treatment for Dogs
How does heartworm treatment work for dogs?
When it comes to heartworm, prevention is better than treatment. Heartworm preventatives work by preventing the development of heartworm larvae in dogs. These medications can be administered monthly or less frequently, depending on the specific product. They work in one or both of the following ways:
- Killing the larvae: Some heartworm preventatives kill the heartworm larvae before they can mature into adult worms. This prevents the larvae from migrating to the heart and lungs and causing damage.
- Preventing the larvae from developing: Other heartworm preventatives prevent the heartworm larvae from developing into adult worms. This means that the larvae will be unable to reproduce and spread the infection to other dogs.
It's important to note that heartworm preventatives are not curative. They can only prevent new heartworm infections. If your dog is already infected with heartworms, you will need to consult with a veterinarian for treatment. A large proportion of heartworm cases in dogs diagnosed in Australia occur in dogs who have been on heartworm prevention but missed one or more doses. If your dog has not been previously given heartworm prevention, or if they have missed any doses, your veterinarian may recommend a heartworm test. Learn more about heartworm in dogs.
How can I tell if my dog has heartworms?
Heartworms can often show no symptoms in the early stages. As the infection progresses, symptoms may include:
- Coughing
- Lethargy
- Weight loss
- Difficulty breathing
- Exercise intolerance
If you suspect your dog may have heartworms, it's crucial to consult a veterinarian for a diagnosis. They may perform blood tests to detect the presence of heartworm antigens.
Is heartworm prevention necessary for indoor dogs?
Yes, heartworm prevention is necessary for indoor dogs. Heartworm larvae are spread by mosquitoes and the disease is present in most areas of Australia. Even if your dog doesn't go outside, mosquitoes can still enter your home and transmit heartworm larvae.
How often should I give my dog heartworm medication?
The frequency of heartworm medication depends on the specific product you choose. Some medications are given monthly, while others are given less frequently. Consult your veterinarian or a Pet Circle vet to determine the appropriate dosing schedule for your dog.
Are there combination flea and heartworm treatments?
Yes, there are many 'all in one' flea, tick, intestinal worm and heartworm treatments available including brands such as Nexgard Spectra, Simparica Trio and Credelio Plus. These products offer convenience and protection against both heartworms and fleas. Ask a Pet Circle vet or check out our article What is the best heartworm treatment for dogs?
