全能狗 and 蚤不到 are both popular products – and produced by the same manufacturer, Merial – but NexGard comes as a flavoured chewable, while Frontline Plus is a spot-on topical treatment.

NexGard chewablesshould only be used to treat dogs. Frontline Plus is available for both dogs and cats, however Frontline Plus for Dogs must not be used on cats.
