Ensure that the dog is rewarded immediately after the behavior has ceased. Precautions: Pressurized container. Keep out of sunlight. Do not expose to temperatures exceeding 50 degrees Celsius. Keep out of reach of children. Keep away from flames. Only use as instructed. Use in short bursts only. Do not apply directly on the skin or swallow. Direct away from dog. Do not leave in vehicles. Replace cap when not in use. The Pet Corrector emits a blast of compressed air, ideal for interrupting undesirable behaviors. Many animals use a 'hiss' sound to ward off predators and the Pet Corrector mimics this sound creating a natural deterrent. A free training guide is included with helpful tips and key do's and don'ts. It is important that the Pet Corrector is used cautiously and responsibly, so as not to traumatize or frighten your dog.
