Just like human children, our dogs go through that dreaded period of social development that strikes fear in the hearts of all parents â adolescence. This is a period where individuals will test boundaries and assert their independence. This is also the period when many dog owners give up, and many dogs end up at the shelter. People forget that this is a frustrating phase that their dog will eventually grow out of. Adolescence is an essential part of growing up, a period for developing the skills necessary to survive, and thrive, in the adult world. When does adolescence begin for your puppy?

Small breed dogs reach social maturity by about one year, giant breed remain adolescent until roughly three.
