Believe it or not, l ike humans, dogs also go through that terrible teenager stage. For dogs, the stage is between the ages of 18 and 20 weeks and it is called the juvenile period. It is during this period when the onset of sexual maturity takes place. The length of the period depends on the specific breed and his individual personality.

Those hormones

Have you ever experienced how young dogs are best friends one day, and the very next day they will be fighting? This is typical of the teenage stage and can be blamed on hormones, which from about 16 weeks start to play a role in their development.

Two of the well-known hormones, testosterone and oestrogen, are found in both males and females, and assist the pup to develop physically. These hormones also play a role in certain potential personality traits and behaviour patterns, and is the cause of big changes in the puppy.
