The Bayer Seresto Flea and Tick Collar makes it easier for you to care for your pet. Just put it on and allow the medication within to keep pests from multiplying. This large dog collar is comfortable for bigger breeds to wear. It’s more convenient than other methods since you don’t have to give pets a pill or rub chemicals on your pet’s fur. Each collar can last for up to eight months at a time. Getting rid of fleas and ticks prevents itching discomfort.
