Although your pet must be protected from ticks and fleas to minimize the risk of many illnesses that ticks carry, There are specific guidelines for avoiding toxic effects when administering these medicines. Substances that pose a threat to insects, like ticks and fleas, could be harmful if they are exposed to animals in huge amounts. For example, a few common flea and tick treatments contain pyrethrins or even Pyrethroids. Pyrethrins belong to a class of medicines made from the chrysanthemum flower or plant, and pyrethroids are the synthetic derivatives of these Pyrethrins. Pyrethrins rarely are found in the products we use daily. However, pyrethroids are often present in products employed in-home use to control insects in addition to the standard anti-flea and tick products. As a result, dogs are frequently exposed to high doses of products to prevent ticks and fleas, as well as lower levels when using these products in the house or outdoors as pesticides, foggers, and Granules. Isoxazolines is a brand new type of tick and flea preventative medication associated with toxicity. These are the first oral tick and flea products developed, and although they are very effective, they may cause toxicity when administered improperly or when an overdose is triggered. The precautions listed above are securely provided the correct dose is used. Isoxazoline-containing preventives include: n Bravecto (topical and oral) n Simparica n Simparica Trio n NexGard n Credelio n
