A fully grown heartworm can grow up to a foot long or even more in length and live in the heart, blood vessels or lungs of dogs, causing heart failure, lung disease and severe damage to other organs.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-left is-layout-flex wp-container-core-buttons-is-layout-fdcfc74e wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link has-vivid-red-background-color has-background wp-element-button\" href=\"https:\/\/www.singaporepetcare.com.sg\/blog\/dog-heartworm-treatment\/\">Dog Heartworm Treatment: What You Should Know<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Causes_Heartworms_in_Dogs\"><\/span><strong>What Causes Heartworms in Dogs<\/strong><strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Heartworm Heartworms in dogs are primarily transmitted by mosquitoes. When an infected mosquito bites a healthy dog, it transmits the heartworm larvae (while transmission, heartworm is at L3 stage and that is not Microfilaria) to the dog. The heartworm larva eventually grows and develops into the adult stage and reproduces. These worms enter the bloodstream and move to the pulmonary arteries, interrupting pulmonary and cardiac functions.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Signs_of_Heartworm_Disease\"><\/span><strong>Signs of Heartworm Disease<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Dogs may not show noticeable symptoms of heartworm disease in the early stages of the infection. The symptoms often appear when the infection persists for a considerable period of time.<\/p>\n\n\n\n<p>Signs of heartworm disease in dogs generally include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Lethargy<\/li>\n\n\n\n<li>Cough<\/li>\n\n\n\n<li>Collapse<\/li>\n\n\n\n<li>Intolerance to exercise<\/li>\n\n\n\n<li>Difficulty in breathing<\/li>\n\n\n\n<li>Weight loss<\/li>\n\n\n\n<li>Excessive panting<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<div class=\"wp-block-buttons is-content-justification-left is-layout-flex wp-container-core-buttons-is-layout-fdcfc74e wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link has-vivid-red-background-color has-background wp-element-button\" href=\"https:\/\/www.singaporepetcare.com.sg\/blog\/caring-heartworm-positive-dog\/\">Navigating Heartworm Treatment: Caring Guide for Heartworm-Positive Dog<\/a><\/div>\n<\/div>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Prevent_Heartworm_Disease_in_Dogs\"><\/span><strong>How to Prevent Heartworm Disease in Dogs?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Treating heartworm disease in dogs can be complicated, expensive, painful, and time-consuming. Therefore, as pet parents, it is important to use effective heartworm preventives to keep these deadly parasites at bay. The products are pocket-friendly, completely safe for dogs and very easy to administer.<\/p>\n\n\n\n<p>While some products only work at preventing heartworm infestation, there are others that also offer protection against fleas, ticks, and intestinal worms.<\/p>\n\n\n\n<p>Some of the most effective heartworm preventives for dogs include Heartgard Plus, NexGard Spectra, Simparica Trio, Interceptor Plus, and Advantage Multi. Seek your veterinarian\u2019s advice to determine a suitable product for your furry baby.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Other_Tips_to_Prevent_Heartworm_Infection\"><\/span><strong>Other Tips to Prevent Heartworm Infection<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Besides using heartworm preventives, you may also implement the following practices to reduce the risk of heartworm infection in dogs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Minimise mosquito exposure<\/li>\n\n\n\n<li>Clean any standing water around your home to prevent mosquito breeding<\/li>\n\n\n\n<li>Avoid taking your dog outdoors during dusk and dawn<\/li>\n\n\n\n<li>Use pet-safe mosquito repellents where appropriate<\/li>\n\n\n\n<li>Groom your dog regularly<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Parting_Words\"><\/span><strong>Parting Words<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p>As a responsible dog parent, you must remain informed about the risks of heartworm disease in dogs, their symptoms and prevention.
