Do not let your dog smell toilet water. Toilet water has a strong smell and is irritating to the dog's nose. Smelling toilet water for a long time will affect the dog's sense of smell, so do not put toilet water and other pungent fragrances in front of the dog. Avoid causing discomfort to your dog. To prevent mosquitoes in summer, you can wear a mosquito repellent bracelet instead of using toilet water.
