Fleas and ticks can be picked up from other infested animals, such as other dogs, cats, or wildlife. Ticks are commonly found in wooded areas, tall grasses, or shrubs, where they attach themselves to passing animals. Year-round prevention is recommended. Some treatments are administered monthly, while others may last for several months. It's important to follow the instructions provided by the specific flea treatment product you choose. Spot-on flea treatments are usually liquid and applied to the skin, typically between the shoulder blades or along the back. These treatments contain insecticides that are absorbed into the dog's body through the skin, entering the bloodstream - when fleas come into contact with the treated area; they are killed or repelled. Flea tablets contain chemicals that are absorbed into the bloodstream and circulate throughout the body. When fleas bite the dog, they are exposed to these chemicals, which either kill the fleas directly or disrupt their life cycle, preventing them from reproducing.
