Puberty in dogs - When everything suddenly changes
Many dog owners find their dog's puberty particularly challenging: the dog "doesn't listen anymore," shows insecurity, or tests boundaries. It's important to know that puberty is not a training issue, but a normal developmental phase.
When does puberty begin in dogs?
Puberty usually begins:
-
in small breeds from about 6 months
-
in large breeds often not until 9–14 months
It can last for several months and is not a linear process.
Typical behavioral changes
During puberty, the brain, hormones, and perception change.
Common signs:
-
Apparent "loss of obedience" --> problems recalling memories
-
Increased distractibility
-
Increased insecurity
-
Increased anxiety and aggression
-
Possible separation anxiety
-
Increased curiosity and exploratory behavior
-
Displacement activities
-
Increased testing of boundaries
Learned signals are not forgotten, but are more difficult to recall.
What your dog needs now
During puberty, your dog needs, above all:
-
Training in calmness and relaxation
-
Clear, fair, and consistent leadership
-
Reliable structures
-
Realistic expectations
-
Training on a relationship level
-
Routines and rituals
-
Predictability
Important:
-
Fewer repetitions
-
More breaks
-
No punishment training
Common mistakes during puberty
-
Excessive demands
-
Inconsistent behavior
-
Unclear leadership
-
Frustration or impatience
-
Comparison with "before"
Puberty is not a regression or deliberate misbehavior on the part of the dog, but rather a period of brain development that your dog needs to adjust to.
Conclusion - Puberty is temporary
End of puberty:
-
A female dog is no longer in puberty once she begins her first heat cycle.
-
A male dog is no longer in puberty once he becomes sexually mature (usually around the time he starts urinating with his hind legs raised).
With understanding, structure and appropriate training, this phase can be well managed – and lays the foundation for a stable adult dog.
