You are feeling pretty proud as you raised your leo puppy through puppyhood. You taught him basic manners, conditioned him to allow his feet and teeth handled, let him explore the world at his own speed, and socialized him extensively.
All is right in his/her world until your lovable sweet pup stops playing nicely and turns into <horrors> an adolescent.
Although not all Leonbergers go through this stage, many do and you should be prepared and not surprised. In this section, you will find topics with tips on getting through this difficult stage and continuing training and caring for your friend. Soon you will end up with the wonderful well trained – well behaved adult dog you know you have.
So you got your leo puppy through puppyhood. You taught him basic manners, conditioned him to allow his feet and teeth handled, let him explore the world at his own speed, and socialized him extensively. And for a while it was smooth sailing.
Then one day a noise emerges from your sweet puppy’s throat as another dog approaches. Rumbling up as though from the depths of some chasm you never knew was in him, it fills the air with an ominous sound.
GGRRROOOWWWLLL! Grumble, growl, snark, ROAR!!! Bark bark bark! Growl!
Soon other behaviors begin to appear in conjunction with these noises. Stiff-legged posturing with the chest pushed out, the head up, ears forward, tail held up high like a plumed sword. He starts kicking up the grass and dirt after he pees. He hikes his leg on inappropriate things, such as cars, other dogs, and people!
Perhaps most worrisome is that while he used to be so easy to take places because he loved everybody
(human and dog alike), now he growls and hackles at other dogs, can’t concentrate in class, and no longer plays nice with others. Not even the girls! What happened to that sweet, easy going, social puppy you had just a few weeks ago? What went wrong? Nothing is wrong. Your puppy has entered the next stage on his way to becoming an adult. Unfortunately, this stage is often the most challenging and frustrating stage. It is adolescence. (cue dramatic music: dun-Dun DUNNNN!)
