By the seventh month the tooth replacement has finished, but he is still curious and loves to play. You can go out for longer walks now, although you should still be careful not to make him jump too much or make sharp turns because his joints and muscles are finishing to form and he could suffer injuries. Take advantage of these walks for his obedience lessons, which can be longer and more demanding.
The greater understanding and recognition gained at this age should allow for the complement of the skills the puppy has learned to help him grow and develop, as well as to avoid boredom.
Puppies that are not spayed or neutered will also begin to exhibit sexual behavior during this period. After 8 months, the puppy can leave the growth food, since the growth rate of its structure is reduced, having practically reached its adult size. Once the puppy has acquired the foundations of the discipline, he can be taught obedience exercises, such as walking with or without a leash, changes of direction, changes in speed, positions (standing, lying down or sitting), immobilities, the call (very important), group work to develop sociability with man and other dogs, etc. Authority is part of the references necessary for the balance of the dog. But while the dog must obey its master, it must not fear him.
At 9 months old and our puppy has entered adolescence, he will be daring and may begin to show some undesirable behaviors, such as jumping on some people, pulling on the leash or insistently asking for things. These behaviors should be reacted quickly with systematic instructions in a firm, clear voice.
