Boarding two dogs together: should they share a kennel?

Usually, yes, as long as they live together and get along. VCA Animal Hospitals’ boarding advice puts it simply: if your dogs get along well, ask whether the kennel has appropriately sized runs so they can be housed together. Most kennels and boarding facilities offer it, and many price the second dog in a shared run lower than a second room. Ask, since policies vary.

There is no national US rule on this; each facility sets its own policy, and the few states that license kennels write it differently. Colorado’s kennel rules are a useful example of how regulators think about it: pets housed together must be compatible, a female in season must not share an enclosure with other animals, and dogs from different households may only be mixed with written owner consent and constant supervision. Kennels elsewhere tend to follow the same logic even when no rule requires it.

Dogs from different households, such as your dog and a friend’s, are a different matter. Most kennels won’t put them in one run overnight, even if they play together at the park.

For compatible dogs, the evidence leans yes. A 2024 study in PLOS ONE followed 61 dogs at a Montana humane society. Dogs housed in pairs showed lip licking, whining and pinned-back ears, three common stress signals, significantly less often than dogs kenneled alone, and they were adopted sooner. Their stress hormone levels also tended to drop more, though the authors called that evidence suggestive rather than conclusive.

Two details from that study matter for your decision. The pairs were screened first, with a dog-to-dog compatibility test and matching by energy and size. And even then, two of the pairs had to be separated for squabbling, both within 36 hours of moving in together, though no dog was injured. The authors note that putting more dogs in a kennel is not automatically better.

Your two dogs have an advantage those shelter dogs didn’t: they already know each other. A bonded housemate is familiar smell, familiar body, and someone to sleep against in a strange place. That’s why a shared run often helps an anxious dog, especially one who leans on the other at home. Our guide to boarding an anxious dog has more on that.

Getting along on your sofa doesn’t guarantee getting along in a small run, in a noisy building, with other dogs walking past the gate. Board them apart, or ask for side-by-side runs, if any of these apply:

• Either dog guards food, chews, toys or a bed. Guarding that you manage easily at home has nowhere to go in a kennel.
• They squabble at home, even occasionally, or one constantly pesters the other.
• One is much smaller, older or frail, and could be knocked over or kept from resting.
• One is sick, recovering, or on medication that needs to be tracked to that dog. Staff need to know who ate what and who is vomiting.
• One is a female in heat, or one is an intact male and the other an intact female. See our guide to boarding an intact dog or a dog in heat.
• They’re on different diets or feeding schedules and one will eat the other’s food.
• One gets wound up by kennel noise and tends to take it out on whoever is nearby.

Side-by-side runs are often the best of both: the dogs can see and smell each other but can’t steal food or crowd each other. Some kennels will also put dogs together by day and split them at night, or the reverse.

You know your dogs better than any temperament test does. For a week or two before the trip, watch them with a kennel run in mind: a small space, a strange building, and no person stepping in between them for hours at a time.

• Do they sleep touching, or at least in the same room? Dogs who choose to rest together usually rest well together at a kennel.
• What happens at mealtime and with chews? A hard stare, a freeze or a growl over a bone is information, not a quirk.
• How do they handle a crate or a car ride together? A shared crate or a back seat is the closest thing at home to a shared run.
• What happens when they’re excited or stressed? Watch the doorbell, a delivery driver, or a dog passing the window. Some pairs turn on each other when they’re aroused and can’t reach the real trigger.
• Does one dog need the other? If one dog paces and cries when the other goes to the vet, that dog is a strong candidate for sharing.

Tell the kennel what you see, good and bad. Staff can only make a sensible housing decision with honest information, and a dog who growls over chews can still share a run if the chews stay home.

Separately, every meal. The ASPCA notes that many owners prevent food conflict by feeding dogs in separate rooms, in crates or behind a barrier, and by making sure each dog gets enough. A good kennel does the same, by taking one dog out of the run to eat or splitting the run with a divider at mealtime.

• Pack each dog’s food separately, in labeled bags or containers with the dog’s name and amount.
• Label medications by dog, with a written schedule.
• Ask how meals are logged. If one dog stops eating, staff need to know which one. Shared bowls make that impossible. Our guide to a dog who won’t eat at boarding covers what to ask.
• Skip high-value chews in a shared run unless staff supervise them.

• How big is the shared run or suite? Both dogs should be able to lie down fully stretched out, apart from each other, at the same time.
• How do you feed dogs who share? You want “apart,” not “side by side from two bowls.”
• What happens if they argue? The right answer is that staff separate them right away and call you, not that they wait and see.
• Are side-by-side runs available if sharing doesn’t work out?
• How is the second dog priced in a shared run versus a separate one?
• Do they go to group play together? Some facilities split housemates by size or play style, which is usually fine.
• Can we do a trial night first? VCA suggests a short stay before a long one. For a pair, it’s the best way to see how they handle kennel life together.

Booking for two also means two sets of vaccine records, two beds and twice the packing. Our what to pack for dog boarding checklist helps.
