    Canine heartworm is passed from dog to dog by the mosquito.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Canine heartworm is indeed passed from dog to dog by mosquitoes. When a mosquito bites an infected dog, it ingests microfilariae (immature heartworms) along with the blood. These microfilariae develop into infective larvae within the mosquito. When the infected mosquito then bites another dog, it transmits these infective larvae into the dog's bloodstream, where they mature into adult heartworms. Therefore, the statement "Canine heartworm is passed from dog to dog by the mosquito" is true.

    Fleas and ticks are indeed the most common external parasites that can infest dogs and cats throughout the year.

    Heartworms obstruct the flow of oxygen to the heart and can affect the lungs, kidneys, and liver.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Heartworms are parasites that can infect dogs and other animals. When heartworms infest the heart, they can obstruct the flow of oxygen to the heart, leading to various health issues. This obstruction can also affect other organs such as the lungs, kidneys, and liver, as these organs rely on a steady supply of oxygen-rich blood. Therefore, the statement that heartworms obstruct the flow of oxygen to the heart and can affect the lungs, kidneys, and liver is true.
