It's generally not recommended to use multiple flea treatments simultaneously unless specifically instructed by your veterinarian. Using multiple treatments simultaneously can increase the risk of adverse effects or overdose. 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. Some spot-on treatments also have additional ingredients to prevent flea eggs from hatching, such as Frontline Plus. Flea tablets, also known as oral flea medications, are ingested by the dog. These 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. If you're considering combining treatments, it's best to consult your vet for guidance and to ensure the safety and effectiveness of the products used.
