Understanding your GSDs behaviour towards us, other dogs or any stimulus for that matter, we can help them. Dogs try to fit in to our lives using natural canine language is the first step to understanding and succeeding in they training and socialisation of your GSD and they go hand in hand. Well socialised dogs are invariably well-trained dogs and vice versa. Thus, all puppies should be socialised. The best socialisation. For dogs is between 4 and 12 weeks of age. During that time, the puppy is very impressionable to social influences and training. If it has good experiences with men, women, children, cats, other dogs etc it is likely to accept them throughout life. If the experiences are absent or unpleasant, it may become apprehensive or adverse to any of them. Therefore, during the period of socialisation, we encourage you to expose your dog to as many types of social events and influences as possible, but always ensure that these experiences are positive for your puppy.
