Teaching your dog to walk on a leash can increase their safety when out and about, reducing the risk of accidents or injuries caused by running away or getting into trouble. Similarly, teaching them to sit and stay can keep them from running out into traffic or getting into fights with other animals. Moreover, training sessions provide mental stimulation for your dog, helping to keep their mind active and engaged. This can reduce the risk of boredom-related behaviors, such as destructive chewing, and help them live a happier, healthier life.
