The Pet Corrector is a dog training aid that interrupts unwanted behaviours instantly with a harmless ‘hiss’ sound. It can be used for behaviours such as excessive barking, jumping up, stealing, and sitting on the furniture. The Pet Corrector sound grabs the dog's attention so the owner can re-train the dog to exhibit positive behaviour instead. It is trusted and recommended by trainers and behaviourists worldwide and includes a comprehensive training guide. The Pet Corrector is available in 3 sizes: 30ml, 50ml, and 200ml, with a convenient holster for the 50ml size. This product is not suitable for puppies, anxious, or noise-sensitive dogs. Avoid placing the aerosol in clothing pockets.
