For training puppies of working breeds, the age from 2 months is considered the most favorable. Adult dogs accept lessons adequately until 2 years of age. In our canine center, there are puppy training courses (from 3 months). A basic training course will keep your dog safe and calm around him. From about 7 months old, when the puppy reaches puberty, he becomes capable of more intense exercise and moderate stress. In the lessons, you can enter the elements of service training from the course of the guard, guard service.
