When do Lakeland Terriers calm down?

The energy curve: what to expect at each stage

Lakeland Terriers don't have an off switch — at least not in the first few years. Here's a realistic timeline of what to expect:

• 0–6 months (puppy): Intensely playful, easily distracted, needs frequent short exercise sessions. Don't over-exercise. Bones and joints are still developing.
• 6–18 months (adolescent): The hardest phase. They have adult energy levels but minimal impulse control. This is when most owners feel most challenged. Consistent training is essential here.
• 18 months–2 years (maturing): Gradually developing the ability to self-regulate. Exercise capacity increases; they can do longer, harder sessions. Training starts to stick better.
• After 2 years (adult): Most owners describe a noticeable shift. The dog is still active and needs significant exercise, but is calmer around the house and more responsive.

Why is my Lakeland Terrier still so hyper?

If your Lakeland Terrier is going through a hyper phase, three things are usually responsible:

• Not enough exercise: A Lakeland Terrier that isn't getting 90–120 minutes of activity per day will burn that energy off differently — usually destructively or noisily.
• Age: If they're under 1.5–2 years, the behaviour is normal. The phase does end.
• Lack of mental stimulation: Physical exercise isn't enough for a mentally active breed. Puzzle feeders, training sessions, and nose work all help drain energy more efficiently.

A Lakeland Terrier that's destructive or restless at home is almost always an under-exercised Lakeland Terrier. The behaviour is a symptom, not a character flaw.

Training through the hyper phase

The most effective approach with a boisterous Lakeland Terrier isn't to wait for them to calm down — it's to train through it. Consistent, patient training with clear expectations works best. Keep sessions short (5–10 minutes) to maintain focus.

Teaching a reliable settle command (where the dog goes to their bed and stays calm on cue) is one of the most valuable things you can train with an active breed. It gives you a tool for managing their energy rather than just waiting for it to dissipate.
