The Teenage Phase! Understanding Canine Adolescence.

We have all been there. You spend months working incredibly hard on your puppy's training, only to hit a brick wall around the half-year mark. Suddenly, your attentive little pup turns into a rebellious teenager who acts like they have never heard their own name before.

Welcome to canine adolescence!

When Will It Happen?

The adolescent phase varies drastically between breeds and individual dogs. As a general guide, dogs enter their teenage phase between 5 to 6 months of age, and this challenging developmental stage can continue until they are around 18 months to 2 years old.

Just like human teenagers, adolescent dogs undergo massive physical, biological, and psychological changes. Their brains are quite literally being rewired, which frequently results in some testing and chaotic new behaviours.

What Can You Expect? (The Teenage Struggle Checklist)

If you are currently experiencing any of these common adolescent struggles, you are certainly not alone:

• The Vanishing Act: All that awesome puppy training you worked so hard on suddenly seems to have completely vanished from their brain.

• Selective Deafness: They develop temporary, periodic deafness. They can’t hear you shouting their name across a quiet field, yet they can still hear a crisp packet opening from two floors downstairs.

• Instant Distraction: They are easily distracted by absolutely everything and anything in their environment.

• The 4:30 AM Wake-Up Club: Their energy levels skyrocket. Because they want to seize the day, waking you up at 4:30 AM suddenly seems like the best idea ever.

• Sudden Spooking: They may enter a secondary "fear period" where they spook easily at everyday objects—even things that never worried them as a young puppy.

• Social Shifting: Your previously super-social puppy might suddenly start testing boundaries or challenging other dogs out on walks.

• Aggressive Chewing: Adult teeth are fully in, meaning standard chews like a pizzle might only last five minutes now. Their desire to chew increases as their jaws develop.

  
  

So, What Can You Do to Survive It?

1. Develop a Sense of Humour

Your rebellious early riser is not intentionally trying to annoy you or get revenge. Their body is flooded with fluctuating hormones, and their brain is developing so fast that they genuinely lose control of their impulses. Try to take a deep breath and relax.

2. Go Right Back to Basics

Now is the time to strip your training back to day one. Concentrate heavily on capturing and rewarding the good choices you want to see more of. Practice the basic skills you originally learned in puppy class, keeping every single training session short, fun, and highly rewarding.

3. Swap Physical Exhaustion for Mental Stimulation

If you have joined the wide-awake club, I am so sorry—it is exhausting. Many owners try to fix this by walking their teen dogs further and further. Don't fall into this trap! You cannot easily tire out a dog in the prime of their youth physically; you are simply building an elite athlete. Instead, add fun feeding enrichment, puzzle toys, and brain games to their day. Mental stimulation lowers their arousal levels and helps them settle.

4. Shift Your Idea of "Socialisation"

Keep exploring different environments, but remember that socialisation does not mean letting your dog play with every dog they see. If your teenager is barking or lunging at passing dogs, create plenty of physical distance so they don't feel the need to shout about it. Remain completely calm, never tell them off for being worried, and focus entirely on making them feel safe and confident.

5. Fall in Love with the Longline

Don't be offended by their sudden lack of recall—they still adore you, but they are genetically hardwired to explore the wider world right now. Clip a long training line onto their harness. This allows you to give them a sense of freedom while preventing them from running off or getting themselves into trouble. Continually practice their recall on the longline, always rewarding them heavily for returning to you.

The good news? This stressful period does not last forever. Take a deep breath, keep training, keep rewarding, and you will get through it. After all, it is just a phase!
