Pet ownership can become complicated if a relationship ends, so it’s worth discussing expectations before getting a dog together.
Ownership disputes are often based on evidence, including paperwork, registrations and financial records.
Ongoing costs and unexpected vet bills can quickly add up, making it important to agree how expenses will be shared.
Talking through future scenarios early can help avoid uncertainty if circumstances change later on.
Getting a dog together is exciting, but pet custody isn't something most couples think to discuss.
Our research shows that these conversations may be more important than they think, as over half (53%) of Brits say their pet would be the hardest thing to give up following a breakup.
Nobody gets a puppy expecting to separate but nearly a third (31%) of couples say they would consider an informal agreement covering pet ownership, costs and responsibilities - a conversation that’s far easier to have earlier rather than during a breakup.
That’s why we've created the Pre-Pup Guide, featuring practical guidance from leading UK family lawyer Tracey Moloney on the conversations you should have before getting a dog with a partner.
The Pre-Pup Guide isn’t intended to be a legally binding agreement. It’s a practical way of having some important conversations, recording what you’ve agreed, and making sure you’re both going into dog ownership with the same expectations.
Who is the legal owner of the dog?
This is probably the first question couples should consider because the answer may not be as obvious as they think. In the eyes of the law, there's no single answer and pet ownership usually comes down to evidence, not just who calls themselves "mum" or "dad".
We naturally talk about pets as members of the family and it’s understandable to form an incredibly strong emotional attachment. But if a relationship ends and there’s a dispute over who should keep the dog, saying “but I’m his mum” or “she’s my baby” isn’t necessarily going to settle the legal question.
There also isn’t necessarily one single piece of paperwork that will determine ownership in every case either. If ownership is disputed, evidence surrounding how the dog was acquired and the parties’ intentions may become important. That might include:
Who bought or adopted the dog?
Whose name is on the purchase or adoption paperwork?
Whose name appears on the microchip?
Whose name is on the pet insurance?
Who is registered with the vet?
Who has paid veterinary bills and other significant expenses?
What evidence is there about what the couple originally intended?
Paying most of the dog’s everyday expenses doesn’t automatically make someone the owner. The sensible approach is to talk about ownership before the dog arrives. Ask the question: Are we getting this dog together, or is one of us going to own it? If you agree that one person will own the dog, make that clear from the outset and try to ensure the paperwork reflects what you’ve agreed.
One of the biggest mistakes couples can make is assuming that one particular document automatically settles everything. Having your name on the microchip is useful evidence if it came to a custody debate, but it isn’t the equivalent of a title deed proving ownership.
Who keeps the dog after a breakup?
People often talk about “custody” of a dog, particularly when a relationship breaks down. Emotionally, that’s completely understandable. Legally, though, the position is different from arrangements for a child.
There’s no automatic principle that says two people who’ve cared for a dog are each entitled to 50% of its time, which might come as quite a shock. Of course, couples are perfectly capable of agreeing their own arrangements after separation.
For some, that might mean the dog lives primarily with one person but regularly spends time with the other. Others manage to make a shared-care arrangement work.
The key is being honest about whether that’s actually practical: what happens if one of you moves 100 miles away, starts a new relationship, or has a change in work circumstances? And, most importantly, is the arrangement actually good for the dog? A dog shouldn’t become a bargaining chip in a relationship breakdown which is exactly why discussing this before getting a dog can be so valuable.
How do couples split their pet expenses?
Dogs are expensive. And it’s much easier to say “we’ll just split everything” before you’ve been presented with an unexpected veterinary bill for several thousand pounds. So, before the excitement of a new puppy takes over, talk about the cost of dog ownership. Start by scoping out estimated costs for those more predictable expenses such as:
Food
Insurance
Routine veterinary treatment
Grooming
Training
Dog walkers or daycare
Kennels or pet sitting
Medication
Toys
Decide whether these costs will genuinely be split 50/50 or whether another arrangement makes more sense. For example, if one partner earns substantially more than the other, you might decide that an equal split isn’t realistic.
Emergency care
There's one conversation that's easy to put off entirely. What happens if your dog ever becomes seriously unwell? Illness doesn't wait for a convenient moment, and treatment decisions often come with a price tag attached and a ticking clock.
You don't need to plan for every possibility, because you can't predict them all. What helps is simply knowing, roughly, how you'd approach it together.
Having that conversation now, while your dog is happily destroying yet another toy, means that if a harder day ever comes, you're not facing it for the first time when you're already worried and under pressure.
Dog care arrangements
Shared ownership doesn’t automatically mean shared responsibility so before getting a dog, talk honestly about what everyday life is going to look like. It’s very easy for both people to imagine themselves cuddling the puppy on the sofa, but is slightly less exciting to discuss who will stand outside on a wet January morning with a poo bag in hand.
So, it’s worth having conversations about who does the morning walk and who does the evening one, who feeds the dog, who takes responsibility for training, who arranges vaccinations and vet appointments, who stays home if the dog is ill, who organises and pays for care when you go away, and who's getting out of bed when the puppy starts crying at 5am.
It doesn't need to be a rigid rota, but agreeing to a rough routine by saying "you do mornings, I'll do evenings" and even jotting it down can save a lot of friction once the novelty of a new puppy wears off.
What happens when life changes?
A dog isn't just a decision for today, it's a commitment that could span a decade or more, and life rarely stays the same for that long. Jobs change, people relocate, relationships evolve, finances shift. None of that is a reason not to get a dog, just a reason to think beyond the present moment when you're planning for one.
Rather than trying to predict the future, it's more useful to ask: how would we handle it if something changed? A few scenarios worth talking through together:
One of you needs to relocate for work
One person can no longer afford their share of the dog's costs
One person can no longer manage the day-to-day care
One of you wants, or needs, to rehome the dog
You separate, and you both want the dog to live with you
One of you moves somewhere that doesn't allow pets
The dog develops long-term medical or care needs
You'll never cover every possibility, and you don't need to. The point is simply to understand where you both stand now, so if things do change, you're navigating it together, not starting from scratch.
The Pre-Pup Questions
Before bringing your dog home, sit down together and answer these questions.
1. Are we getting this dog jointly, or will one of us be the owner?
2. Whose name will appear on the purchase or adoption paperwork?
3. Whose name will be registered on the microchip, insurance and veterinary records?
4. How are we going to divide the everyday costs?
5. Are we taking out pet insurance and who will pay for it?
6. Who will take responsibility for the dog’s everyday care?
7. How will we make important decisions about the dog’s health and welfare?
8. What happens if one of us can no longer afford our agreed contribution?
9. What happens if one of us can no longer provide our share of the care?
And perhaps the most important question:
10. If everything changes, what arrangement would genuinely be best for the dog?
A Pre-Pup conversation isn’t about taking the excitement out of getting a dog, if anything, it’s the opposite. It's a sign you're thinking seriously about a shared responsibility, not just an exciting purchase.
Most couples will hopefully never need to rely on the conversation they’ve had about what happens following separation. But if they do, having discussed it early, before things ever got difficult, can make a difficult situation just a little easier.
The Pre-Pup is intended as a practical conversation guide and is not a legally binding agreement or substitute for legal advice.
FAQs
Do you need to register a change of dog ownership anywhere?
There's no official ownership register in the same way as, say, a car log book. However, it's worth updating the microchip database, the vet's records and the insurance policy so they reflect who the dog actually lives with and who's responsible for them.
Does being named on a dog's microchip make you the legal owner?
A microchip can provide useful evidence of ownership, but it isn't legally proof on its own. If ownership is disputed, a range of evidence may be considered, including purchase records, insurance details, veterinary records and the intentions of those involved.
Should both partners be named on pet insurance?
This will depend on the insurer and the arrangements agreed between the couple. If both partners will be sharing responsibility for the dog, it's worth discussing whose name the policy will be under, who will pay the premiums, who will manage claims and how any excess payments will be covered before taking out cover.

What our expert says...
“When a relationship breaks down, pets can become a surprisingly difficult point of disagreement. Unlike financial assets, a pet is a living, emotional part of the family, which can make decisions about where they should live particularly challenging. Having an honest conversation about ownership and responsibilities before getting a pet may feel slightly unromantic, but it can help avoid uncertainty and conflict further down the line.”
