Petstoral No-Go Training Spray: Correct Unwanted Urination and Scratching and Biting. Here's how it works: 1. Correction with No-Go Spray. Simply spray No-Go Training Spray on the areas where your dog has urinated unwantedly, Scratching, Biting and combine it with gestures to drive the pet away from those spots. 2. Repetition Leads to Avoidance. Repeat this training multiple times. Over time, your pet will learn to stay away from those areas, reducing the likelihood of unwanted urination and Scratching & Biting. 3. Potty Training with Positive Reinforcement. After meals, guide your pet to the designated potty area and use Potty Training Spray (part of the Petstoral set). The unique scent will attract your pet to relieve itself in that specific spot. With repeated training, your pet will develop a habit of defecating and urinating in the designated area. 4. Enhance Training with Rewards. Combining rewards during the training process will enhance the effectiveness of the spray, making the learning experience more positive for your pet.
