Your dog has been desexed prior to puberty and so will not mature fully in many
ways. He is likely to remain more playful and submissive in his approach to your
family and to other dogs than he would if he was sexually active. Fortunately however, you can expect your dog to stop chewing and digging. Your dog is likely
to be less active at this stage and will need less food than during adolescence.
