How is heartworm in dogs spread?
Heartworms are transmitted from one dog to another by mosquitoes, which pick up the tiny microfilariae when they bite an infected dog. The microfilariae develop in the mosquito and are transmitted when the infected mosquito bites another dog. The heartworm larvae then migrate through the dog’s tissues and circulatory system, eventually reaching the heart and lungs where they grow into adult heartworms.
What are the signs of heartworm disease?
Signs of heartworm disease can be subtle and difficult to detect until its later stages. As the disease progresses, signs may begin to appear. Contact your veterinarian immediately if you notice coughing, difficulty breathing, sluggishness and less energy for exercise in your dog. Adult heartworm cause serious harm to your dog's heart and lungs, and if left untreated, heartworm disease can result in severe and potentially fatal disease.
Why is heartworm disease dangerous?
