Puppy Exercise — How Much Is Too Much?

You love your puppy. You want them healthy, happy, and well-exercised. So you're doing everything right… aren't you?

Maybe. But the number one mistake well-meaning owners make? Doing too much, too soon.

Why puppies aren't just small dogs

Here's the thing nobody puts on the cute puppy calendar. Your puppy's skeleton isn't finished yet.

Puppies have growth plates — areas of soft, developing cartilage at the ends of their bones. These are the bits responsible for making your tiny fluffball into a fully grown dog. And until they close (which happens somewhere between 12 and 18 months depending on breed), they are vulnerable. Repetitive impact, sustained exercise, and forced movement can cause real damage to these plates — damage that can show up as joint problems, pain, and lameness later in life.

The heartbreaking part? Most of it happens before the dog ever shows a single sign of discomfort.

The five-minute rule — helpful starting point, not gospel

You've probably heard of it. Five minutes of exercise per month of age, twice a day. So a four-month-old pup gets 20 minutes, twice daily.

It's a useful rough guide. But it's not the whole story.

Not all exercise is equal. A gentle potter around the garden sniffing every blade of grass? Very different from 20 minutes of fetch on hard ground or jogging alongside a bike. The type of movement matters just as much as the duration.

Every dog is different. A four-month-old Chihuahua and a four-month-old Great Dane are not the same. Larger and giant breeds have longer growth plate closure timelines and carry far more body weight through those vulnerable joints. They need even more caution, not less.

What to avoid (and why)

Repetitive, high-impact exercise.  Fetch is the big one. Ball-chasing involves explosive acceleration, sharp turns, sudden stops, and repeated jumping. Young joints are not built for that yet. It's not about being boring — it's about building a body that lasts.

Long, continuous walks on hard surfaces.  Roads and pavements are unforgiving. Short, varied walks on mixed terrain are far kinder.

Forced exercise.  Running alongside you, keeping pace on a lead, or being pushed beyond their natural stopping point. Puppies will often want to keep going — they don't have great self-regulation yet. That's your job.

Jumping up and down from furniture or out of cars.  The landing forces involved are significant for a small developing skeleton. Ramps and lifts aren't just for older dogs.

Dog parks with boisterous older dogs.  Uncontrolled rough play, especially with larger dogs, puts unpredictable forces through little bodies.

What does good puppy exercise actually look like?

Short, frequent, varied. That's your mantra.

Let them lead the pace. Sniff-led walks where your puppy gets to stop, investigate, and mooch are brilliant — mentally tiring and physically gentle.

Free play in a safe, soft space. Let them choose when to run and when to stop. Garden play on grass is ideal.

Training sessions. Short, positive training is mentally exhausting in the best possible way. Sit, recall, name recognition — ten minutes of that and most puppies are ready for a nap.

Enrichment. Snuffle mats, scatter feeding in the garden, puzzle feeders, licki mats. These engage your puppy's brain, keep them occupied, and require almost no physical exertion. Win, win, win.

Signs you might be overdoing it

Your puppy is telling you things all the time. Here's what to look out for:

• Stiffness after rest — especially after a walk or play session, if they're slow to get up or moving awkwardly, that's worth noting.

• Reluctance to exercise — puppies are generally enthusiastic. If yours is suddenly reluctant, something may be uncomfortable.

• Subtle changes in gait — a slight hitch, a brief bunny hop, favouring one leg. These can be easy to miss. Slow motion video of your puppy trotting can be really useful.

• Excessive tiredness — a little sleepiness after exercise is normal. Exhaustion that lasts hours isn't.

  
  

If you're noticing any of these, speak to your vet. And if you want to get ahead of any issues before they become problems, a veterinary physiotherapy assessment is a great option — not just for injured dogs, but for building healthy movement patterns from the start.

The bigger picture

Building a physically resilient dog isn't about doing the most exercise. It's about doing the right exercise at the right time.

The habits you build in puppyhood — the movement patterns, the joint loading, the muscle development — lay the foundation for everything that comes after. A puppy who is exercised thoughtfully is far more likely to be a dog who stays active, comfortable, and happy well into old age.

That's not a small thing. That's everything.
