At first glance, it might seem unfair to separate dogs based on size.

After all, dogs don’t necessarily care whether their playmate is big or small. Some small dogs absolutely love playing with large dogs, and some big dogs are incredibly gentle.

So why do we separate our big and small dogs at daycare?

Because safe play isn’t just about whether a dog is friendly. It’s also about size, strength, play style, energy levels and what can happen when things get overly exciting.

At Up for Paws, separating dogs by size is one of the ways we create a safer and more comfortable environment for everyone.

Friendly Doesn’t Always Mean Safe

One of the most important things to understand about dog play is that a dog doesn’t have to be aggressive to accidentally hurt another dog.

Imagine a 30kg dog getting excited and sprinting towards a 5kg dog.

The larger dog may simply be trying to play.

But if that play involves jumping, chasing, body-slamming or a quick turn, the smaller dog can be at a significant physical disadvantage.

The difference isn’t necessarily temperament.

It’s physics.

A large dog can cause an accidental injury to a much smaller dog simply because of the difference in body size and strength.

That’s why responsible daycare management involves thinking beyond whether individual dogs are “friendly.”

Dogs Play Differently

Another reason we separate dogs by size is that play styles can be very different.

Some larger dogs enjoy rough-and-tumble play: chasing, wrestling, body contact and energetic games.

A small dog may prefer shorter bursts of running, chasing a toy or interacting more gently.

Of course, there are plenty of exceptions.

Some small dogs are incredibly energetic, while some giant breeds are happy to lie around all day.

That’s why size is only one factor we consider when deciding which dogs should play together.

Temperament and play style matter too.

A Small Dog Can Be Overwhelmed Without a Fight

People sometimes assume that a dog is only at risk if another dog becomes aggressive.

That’s not necessarily true.

A small dog surrounded by much larger, highly energetic dogs may become overwhelmed even if every dog involved is friendly.

Repeated chasing, being constantly approached or simply having a larger dog hovering over them can be stressful.

And stress doesn’t always look dramatic.

Some dogs may withdraw, hide, avoid interaction or repeatedly try to move away.

Creating appropriately sized playgroups can give smaller dogs more opportunities to interact at a pace that feels comfortable to them.

But Small Dogs Aren’t Always Fragile!

This is important too.

Small doesn’t automatically mean nervous.

And big doesn’t automatically mean rough.

We don’t believe in putting every dog into a category based purely on their weight or breed.

We’ve met tiny dogs with enormous personalities and large dogs who are complete gentle giants.

The purpose of separating dogs by size isn’t to label them. It’s to manage the environment around them.

Think of it as an additional layer of safety.

Why Size Matters During Excited Play

Dogs don’t always move gently when they’re excited.

They run.

They chase.

They jump.

They change direction suddenly.

They wrestle.

They play-bite.

They can go from calm to extremely energetic in seconds.

When dogs are similar in size, the physical consequences of that interaction are generally more comparable.

When there’s a very large difference in size, the same interaction can have very different consequences.

For example, a large dog putting a paw over another large dog might be completely normal play.

The same movement directed at a tiny dog could knock them over.

That is why good daycare management considers not only intention, but also potential impact.

Separation Doesn’t Mean Isolation

When we say we separate big and small dogs, that doesn’t mean every dog is kept alone.

Quite the opposite.

Dogs still get opportunities for supervised social interaction, play and enrichment — they’re simply grouped in a way that makes sense for their size, temperament and play style.

The objective isn’t to remove socialisation.

It’s to make socialisation safer.

What About Dogs of Similar Size but Different Personalities?

Size isn’t the only thing that matters.

Two dogs can be the same size and still be completely incompatible playmates.

One may love wrestling.

The other may prefer to sniff and explore.

One may be incredibly energetic.

The other may become overwhelmed by constant chasing.

That’s why responsible daycare isn’t simply about putting “small dogs together” and “big dogs together.”

The individual dog still matters.

We look at things such as temperament, energy level, confidence, play style and how each dog responds to other dogs.

Why We Choose Separate Playgroups at Up for Paws

Our approach is simple:

We’d rather prevent a problem than wait for one to happen.

Separating dogs into appropriately sized groups gives us another way to manage risk while allowing dogs to enjoy everything daycare has to offer.

For us, daycare isn’t about putting as many dogs together as possible.

It’s about creating an environment where dogs can:

• Play safely
• Socialise appropriately
• Have fun
• Take breaks
• Rest when they need to
• Feel comfortable around other dogs

And sometimes, keeping dogs apart by size is an important part of achieving that.

Does Your Dog Have to Be Big or Small to Join?

Not necessarily.

Every dog is assessed individually, and the right group depends on more than weight alone.

We’re interested in the whole dog — their personality, confidence, energy and how they interact with others.

Because ultimately, good daycare isn’t about finding the biggest group your dog can join.

It’s about finding the right group for your dog.
