Adding a second dog is usually presented as a kindness to the first one. Sometimes it is. Often it is a decision made by an owner who feels guilty about long working days, and in that case it doubles the problem rather than halving it: two dogs alone for eleven hours instead of one.
The decision is worth making deliberately, because it is very hard to reverse and because the first six months determine whether you end up with a household that runs itself or one that needs managing every day.
Reasons that work, and reasons that do not
Good reasons. You want another dog and have the time, money and space. Your existing dog is demonstrably social, seeks out other dogs, plays well and is calmer after dog company. Somebody is home for a decent part of the day, or paid cover is already in place.
Poor reasons. Guilt about the hours your dog spends alone. Hoping that a second dog will treat the first one's separation anxiety, which it will not, because that anxiety is about you. Wanting a companion for an elderly dog that has stopped playing, which frequently makes the last years of its life harder rather than better. Replacing a dog that has recently died, before the household has settled.
Dogs that panic when their owner leaves usually panic just as hard with another dog in the room. Film it before you decide.
The honest arithmetic
Two dogs means two sets of vaccinations, two wormings, two parasite treatments, two insurance premiums and, a second annual dog tax at your commune's rate. Both animals have to be declared to your commune and both added to your civil liability cover.
It also means more time, not the same time spread across two dogs. Separate training sessions in the early months, separate walks for the first weeks, and two dogs to manage in a lift, on a narrow pavement and at the vet. For holidays, both boarding and in-home care cost more, although in-home care is usually priced per stay rather than per dog, which narrows the gap considerably for a two-dog household.
And the medical arithmetic is unforgiving: two dogs of similar age will need expensive care at roughly the same time, ten years from now.
Choosing the second dog
Match energy and play style more carefully than breed or looks. A boisterous adolescent with an eleven-year-old is a difficult household. A dog who plays by body-slamming with one who plays by chasing tends to produce misunderstandings rather than fights, but it produces a lot of them.
Opposite sexes are often, though not always, an easier combination, particularly with two strong characters. Size difference matters for safety: a single bad moment between a forty-kilo dog and a five-kilo dog has very different consequences at each end.
Arrange a meeting on neutral ground before committing, and ask a good rescue to do the introduction properly rather than in a car park in five minutes. If your dog has ever fought with another dog, seek professional advice before adding one to the household permanently.
The introduction
Neutral ground first. Not your flat, not your street. Two handlers, two leads, a parallel walk at a distance where both dogs are relaxed, gradually converging. Twenty minutes of walking side by side does more than an hour of sniffing face to face.
Then the home, carefully. Pick up everything worth fighting over before the new dog arrives: bones, toys, food bowls, the favourite bed. Let the new dog explore while the resident dog is elsewhere, then swap.
Separate absolutely everything at first. Feed in different rooms, behind a closed door. Give chews separately. Provide more resting places than dogs, in different rooms. Walk them separately for the first week or two, so each dog still gets your undivided attention and so you can assess each one on its own.
Supervise or separate. For the first weeks, the dogs are either supervised or behind a gate. Most serious fights in new multi-dog households happen in the first month, in the owner's absence, over a resource.
The first three months
Expect a honeymoon followed by a wobble. Many new dogs are polite and subdued for two weeks and start expressing preferences in week three, exactly as they do in a single-dog household. That is the dog settling, not the arrangement failing.
Protect the resident dog's routine: the same walk time, the same sleeping place, the same bed, the same order of things. And train separately, ten minutes each per day. Two dogs trained only together learn to do everything as a pair, including ignoring you as a pair.
Watch for the quiet problems rather than the loud ones: one dog consistently displaced from the water bowl, one dog no longer approaching you when the other is present, one dog that has stopped playing. Growling over a bone is normal communication and is managed by removing the competition. Silent stiffness, staring and blocking are the signs that need professional attention.
Two dogs in a Luxembourg flat
Practical points specific to apartment living. Two dogs on one lead in a lift is difficult; use two leads and short ones, and let another resident take the lift alone if they would rather. Barking is amplified by a second dog, and a neighbour who tolerated one will not necessarily tolerate two. Stairs and narrow corridors are where a scuffle becomes a bite, so manage doorways deliberately: one dog through at a time.
Walking is the other consideration. Two dogs of different ages rarely want the same walk, and the compromise usually shortchanges one of them. That is one reason many two-dog households here book a midday walk for both together, which is the only group walking I do, and a separate longer outing for the younger one at the weekend.
If it is not working
Give it three months of proper management before concluding anything, and get help early rather than late if there has been a fight with injuries. Most two-dog households settle. The ones that do not are usually the ones where the dogs were left to work it out themselves, which is advice that sounds robust and produces the worst outcomes.
