Heartworm in dogs is caused when they receive a bite from an infected mosquito. Contrary to myths you may have heard, it’s not contracted in any other way, and there is no way for an infected dog to pass heartworm on to another dog. Heartworm develops when the larvae of the infected mosquito lodge themselves into the heart, lungs and blood vessels of your dog. It can take months for heartworm to develop after your dog has been infected.
Treatment can be sought, but it’s both difficult and expensive. For this reason, animal care professionals strongly recommend preventive medication and routine blood work to ensure your dog is not suffering the effects of heartworm. Testing is not expensive, and can be performed at most vet clinics. To get more information about how you can prevent heartworm in your dog, talk to a veterinarian about your options.
