What is the hardest age with a German Shepherd?

Most German Shepherd owners agree the trickiest phase hits between 6 and 18 months—this is when your cute pup turns into a rebellious teen. You’ll notice sudden bursts of energy that make morning walks feel like a tug - of - war, and they might start chewing through your favorite sneakers or ignoring your “come” command mid - chase after a squirrel. It’s not just about patience; this age tests your ability to stay consistent, especially with a breed as intelligent and strong - willed as GSDs.

This teenage phase brings unique challenges tied to their growing bodies and minds. German Shepherds are working dogs, so without enough mental and physical stimulation, they get bored—and boredom leads to trouble. You might find them digging up the flower beds or barking excessively at neighbors, which can quickly become a problem in areas with strict noise ordinances common in many U.S. suburbs and European cities.

Speaking of rules, this age is when you need to double - down on compliance with local dog laws. In the EU, for example, your GSD must have a pet passport and up - to - date rabies vaccinations by 12 weeks, but as they get older, leash laws become even more critical—many public spaces, like city parks in Germany or France, require dogs over 6 months to be on a secure leash at all times. In the U.S., states like California and New York have strict liability laws for dog bites, so training your teen GSD to socialize with other dogs and people isn’t just helpful—it’s legally smart.

Training during this phase needs to lean into positive reinforcement, not punishment. GSDs respond best to rewards like their favorite treats or extra playtime when they follow commands. Skipping training sessions now can lead to lifelong behavioral issues, like pulling on the leash or being overly protective. It’s also a good time to check if your local area has mandatory obedience classes—some U.S. counties and EU regions recommend them for large breeds like German Shepherds to promote community safety.

A friend in Oregon learned this the hard way: her 10 - month - old GSD started jumping on delivery drivers, and she got a warning from animal control. After enrolling in a local training program that focused on impulse control, they turned things around. This kind of real - world scenario is common—teenage GSDs don’t mean to be naughty; they’re just figuring out their place in the world and need clear guidance.

Sticking through this phase pays off. By 18 to 24 months, your German Shepherd will mellow out, and all that training will turn them into the loyal, well - behaved companion they’re known to be. Just remember to stay consistent, follow local laws, and give them plenty of love—your patience now will result in a lifelong bond that makes every tough moment worth it.
