Help! My 14-Month-Old Dog Suddenly Started Destroying Things

Many dog owners breathe a sigh of relief after surviving the teething stage and early puppy training. But then something unexpected happens around 12 to 18 months: their sweet, well-behaved pup turns into a furry tornado of destruction.

At this age, your dog is in what’s often referred to as adolescence—and just like with teenagers, it can be a bit rocky.

Let’s break down why your dog might suddenly be acting out and how you can handle it.

Why Is My 14-Month-Old Dog Suddenly Destructive?

1. Adolescence Has Arrived

At this age, your dog is still maturing emotionally and behaviorally. They’re full of energy, curiosity, and independence—but may also be testing boundaries or forgetting the rules you worked so hard to teach.

2. Excess Energy

Dogs at this age are often brimming with energy. If they don’t have enough physical or mental stimulation, that energy will find a way out—usually through chewing, digging, or shredding whatever’s nearby.

3. Boredom

A bored dog is a destructive dog. If your dog doesn’t have something to do, they’ll create their own form of entertainment… which usually involves your stuff.

4. Separation Anxiety or Attention-Seeking

If your dog is left alone for long periods or feels neglected, they may act out to relieve anxiety or simply get your attention. Even negative attention (like scolding) can reinforce the behavior.

5. Lack of Structure or Reinforcement

Dogs at this stage often “forget” their training or push the limits. If rules and routines have become inconsistent, your dog may start acting out just to see what they can get away with.

What Can You Do About It?

1. Increase Physical Exercise

A 14-month-old dog needs regular, structured activity. Long walks, off-leash time (in safe areas), or play sessions like fetch or tug-of-war can help burn off excess energy.

Tip: Consider a hands-free leash system to make your daily walks easier and more enjoyable.

2. Provide Mental Stimulation

Physical activity alone isn’t always enough. Rotate toys, introduce puzzle feeders, and work on new tricks to keep your dog mentally engaged.

3. Revisit Training Basics

Don’t assume your dog remembers all their early training. Go back to basics—sit, stay, leave it, drop it—and reinforce them daily. Use positive reinforcement like treats and praise to encourage good choices.

4. Dog-Proof Your Space

If certain items are repeatedly being destroyed, it’s time to limit access. Use baby gates, close doors, and keep valuables out of reach during this phase.

5. Create a Safe “Calm Zone”

Sometimes, dogs just need a place to chill out. A cozy crate or quiet room with a bed, toys, and water can be a helpful place for rest and decompression.

6. Avoid Harsh Punishment

Yelling or scolding can increase anxiety and won’t help your dog understand what they’re doing wrong—especially if you don’t catch them in the act. Instead, calmly redirect them to an appropriate activity or toy.

7. Consider Professional Help

If the behavior continues or worsens, a certified trainer or behaviorist can help you troubleshoot and create a customized plan for your dog’s needs.

When Will This Phase End?

The adolescent phase doesn’t last forever—most dogs begin to settle down around 18–24 months. With patience, consistency, and a good dose of humor, you’ll get through it. And once you do, you’ll have a well-rounded adult dog on your hands.

Final Thoughts

A destructive 14-month-old dog isn’t “bad”—they’re just going through a normal (and temporary) phase of development. By giving them the right outlets for their energy, reinforcing good habits, and staying calm through the chaos, you’ll help them grow into a confident and well-behaved adult.

Hang in there—you’ve got this. And so does your dog. 🐾
