How would you house multiple dogs?

I want to get something off my chest first. I am here to prove that despite popular sentiment, maths is where many solutions to your problems lie. So today we are going to do some basic maths and take a deep dive into the operational and welfare implications of different models in group housing of dogs — including space management, stress reduction, and why “just throwing them all in together” is not a strategy, it’s a liability.

Let’s be real: if you’re running a shelter, a boarding facility, or even a multi-dog household, you’re not just managing animals — you’re managing space, behavior, and sanity. And yes, that means math. Not calculus. Not trigonometry. Just multiplication, division, and a little common sense.

We’re going to look at three models:

1. Kennel and Run Sharing (All or multiple dogs in one space)

2. Separate Kennels, Shared Runs (Private sleeping, communal play)

3. Single Housing + Individual Runs (The gold standard for welfare, but costly)

—

MODEL 1: KENNEL AND RUN SHARING — “THE BUNCH”

This is the “everyone sleeps, eats, and poops together” model. It’s cheap. It’s easy. It’s also a behavioral (and veterinary) time bomb.

Let’s say you’ve got 3 dogs. According to the formula from Maltese dog-keeping regulations (which are actually pretty sensible), the minimum area for N dogs in one enclosure is (1 + N) × 2.4 m². So for 3 dogs: (1 + 3) × 2.4 = 19.2 m². That’s one big room just for "sleeping", as they will spend way more than downtime in most kennel situations. And the shortest side must be at least 1.8m — so you’re looking at something like 3.2m x 6m, or 4m x 4.8m.

But here’s the problem: dogs aren’t furniture. They need personal space, privacy, escape routes, and undisturbed sleep. In one big room, you get:

- Resource guarding (food, toys, beds)

- Less enrichment (to avoid triggering resource guarding)

- Stress spikes during feeding or play or cuddles

- No retreat option for anxious dogs

- Higher risk of disease transmission

- Fewer options to identify whose vomitus/runny poop showed up this morning

- Delayed diagnosis and treatment

- More cleanup, more conflict, more management headaches

Operational cost? Low. Welfare cost? High.

MODEL 2: SEPARATE KENNELS, SHARED RUNS — “THE COMPROMISE”

Each dog has its own sleeping space (kennel), but they rotate into a shared run for exercise and socialization.

For 3 dogs, each kennel needs to be (1 + 1) × 2.4 = 4.8 m². So 3 kennels = 14.4 m² total for sleeping.

Benefits:

- Dogs get privacy at rest

- You can manage social groups (e.g., only let compatible dogs run together)

- Healthy groups can use the same run on a schedule

- Easier to monitor individual behavior

- Easier to control an incident

- Less stress than full cohabitation

Downsides:

- Requires staff to manage rotation

- Still risk of conflict in shared space

- Not ideal for dogs with high anxiety or aggression but down the line in rehab, maybe, if they want to.

This model is a solid middle ground — especially for shelters with limited space.

MODEL 3: SINGLE HOUSING + INDIVIDUAL RUNS — “THE LUXURY OPTION”

Each dog gets its own kennel AND its own run. No sharing. No compromise.

For 3 dogs: 3 × 4.8 m² = 14.4 m² for kennels, and 3 × 4.8 m² = 14.4 m² for runs. Total = 28.8 m².

That’s more than double the space of Model 1, and 1.5x Model 2.

But here’s the payoff and when it's the benchmark:

- Zero forced social interaction

- No competition for resources

- Easier to manage medical or behavioral issues

- Lower stress = better behavior = fewer incidents

- Dogs can decompress, rest, and feel safe

- Ideal for intake disease and behavioural quarantine

- Ideal for highly stressed abuse/neglect cases who need a mental space for their nervous system to reset

- Ideal for boarding where dogs shouldn't mix

This is the model you see in high-end boarding facilities, and behavior rehab centers. It’s expensive. It’s space-intensive and requires a lot of human input for enrichment, social stimulation, exercise, basically everything they normally get from socialising. Have a look at my blog from yesterday where I explore the 5 welfare needs of animals, including natural behaviour and social groups.

SO WHAT’S THE VERDICT?

If you’re running a shelter, Model 2 is your sweet spot for main housing— if you have the staff to manage it. If you’re a multi-dog household? It depends! What do you make of this for your set up?

And if you’re still saying “math doesn’t matter” — well, you’re not just ignoring numbers. You’re ignoring welfare.

Dogs aren’t math problems. But the spaces we put them in? Those are.

P.S. If you’re using this formula in Malta, check the actual regulation text — I’m working off the Keeping of Dogs Regulations from Legislation.mt. Always verify local laws. And if you’re not in Malta? Adapt the formula to your local standards. Math is universal. Regulations are not.
