You brought home a sweet, playful puppy who followed you everywhere, eager to learn and please. But now? Theyѻýve started ignoring cues, barking at things they never used to notice, and seem to have selective hearingѻýespecially when you call them at the park.

Sound familiar? Welcome to the teenage dog phase.

This stage, also called adolescence, can begin around six months of age for some breeds and last well into the second year of life. Itѻýs a natural part of your dogѻýs development, but it can leave even the most patient guardians feeling confused or overwhelmed.

Whatѻýs happening with your puppy?

Just like human teens, adolescent dogs are undergoing big changesѻýhormonally, physically, and emotionally. Their brains are still developing, and theyѻýre starting to test boundaries, explore the world with more independence, and sometimes act like theyѻýve never heard the word ѻýsitѻý before. Itѻýs not that theyѻýve forgotten their trainingѻýtheyѻýre just distracted, overstimulated, and working through their new adolescent brain chemistry.

One of the most surprising shifts during this time can be fearfulness or reactivity. A dog who once loved everyone might suddenly bark at strangers or avoid new experiences. This is often due to a secondary fear period that occurs during adolescence. Itѻýs temporary, but how you respond makes a big difference.

This phase doesnѻýt last. But it does matter

The good news? Your goofy, sometimes frustrating teenage dog will grow up. The challenging behavioursѻýpulling on leash, ignoring cues, barking at other dogsѻýarenѻýt signs of a ѻýbad dog.ѻý Theyѻýre signs of a young dog who needs support, structure, and understanding while their brain catches up to their body.

What does matter is how we guide them through it. Without clear, compassionate support, those temporary behaviours can become long-term habits. Think of this stage as your second chance to develop the adult dog you want to live with.

How to help your teenage dog thrive

1. Stay patient and keep training positive

Even if your dog suddenly acts like theyѻýve never heard a cue before, stay calm. Go back to basics in quiet environments, reward the effort, and keep sessions short and fun.

2. Support, donѻýt scold

Your dog isnѻýt being stubbornѻýtheyѻýre struggling. Scolding, yanking on the leash, or using punishment can actually make things worse, especially if fear is involved. Focus on building trust and confidence instead.

3. Give them safe, positive experiences

Keep socialization going, but donѻýt overwhelm them. Let your dog observe the world at their own pace and reward the behaviour. This helps reduce the chances of reactivity or long-term fearfulness.

4. Burn off that energy

Teenage dogs need outlets. Walks, sniffing, training games, puzzles, and even tug can help meet their mental and physical needs.

5. Donѻýt be afraid to ask for help

If your dogѻýs behaviour becomes unmanageable or concerning, reach out to a force-free trainer. Youѻýre not aloneѻýand itѻýs never too early to get support.

Youѻýve got this

Raising a teenage dog can be messy, funny, and sometimes a little maddeningѻýbut itѻýs also a beautiful opportunity. With patience, kindness, and consistency, youѻýll help your dog grow into the confident, well-mannered adult theyѻýre meant to be.
