This is a great post by Dr. Dr. Lisa Radosta!
We do see an explosion of clientele between 1-3 years of age! Oftentime around 8 mos + is where things start to escalate.
If you are seeing problems in your puppies, for example- resource guarding-
‼️ 📣 THEY WILL NOT ‘JUST GROW OUT OF IT’!!!
It will only (very likely) get worse.
So- if you see something- call a qualified, experienced trainer, and say something!
The best way to address behavior issues is by addressing them early- as soon as you see them- and continuing to work on it/them throughout the adolescent period (which could be 3-4 years of age).
When dogs enter adolescence, many families are surprised by how quickly behavior can seem to deteriorate. A dog who was previously manageable may become reactive on walks, resistant to handling, more sensitive to strangers, more intense around food or toys, or emotionally unpredictable at home. It often feels as though something suddenly went wrong.
From a veterinary behavior perspective, that is rarely the case.
Most adolescent behavior problems are not new. They are the result of patterns that have been developing quietly since puppyhood. Early fear responses, tension around bones, discomfort with handling, overarousal, and avoidance behaviors are frequently present long before adolescence, but they are minimized because the dog is young, small, or still “learning.” Over time, those responses become part of the dog’s emotional repertoire.
During this stage, the brain regions responsible for impulse control and emotional regulation are changing. This is also a time when pet parents are on autopilot; they aren't reinforcing behaviors, providing structure or training.
This is why behavior problems often appear to “explode” during this period, but they really aren't.
Adolescent dogs are not being difficult on purpose. They are neurologically unfinished.
How they are supported during this period has lasting consequences.
Support them with structure, patience, consistency and positive reinforcement training.
