AIBU to keep my sister’s former dog after she moved back?

I’ve name changed as this is a very outing situation. I wasn’t sure whether to post in the dog house but opted for here.

My sister moved abroad 7 months ago due to her husband’s work. They were originally moving for 3 years but my sister didn’t settle there so they’ve split up and my sister has come back with her children.

When they were planning to leave, they asked if we would look after their dog temporarily for the 3 years and they would have him back when they returned. We thought it over and said we would only take the dog if it was permanent. We knew our children would get attached to the dog and didn’t want them being upset when the dog had to be returned. They looked at other options but eventually agreed, reluctantly. Microchip/ownership was changed over to us and we pay all costs.

My sister is now back much sooner than planned with her kids and they’ve asked for the dog back. He is our dog now and completely settled in with us. We would all be heartbroken to not have him.

My whole family is piling on guilt and pressure for us to give the dog back. They’re using the kids to emotionally manipulate and saying my sister has enough on her plate with the split and having her dog back would help the children settle back home. They’re also saying that as the dog has only been with us for 7 months, we should give him back as it’s not long enough for him to have settled. My niece and nephew are upset but that isn’t surprising with moving countries, being without their dad and now moving back all within a few months.

We don’t intend to give him back. He isn’t a toy to be passed around when people change their minds and plans change and he has a great life with us. If we don’t give him back, I think it will cause a permanent rift in our family. Are we being unreasonable to keep the dog because we can’t give him up? I don’t believe it’s in his best interests anyway.

I think it’s in the dog’s best interests to stay with you. I think your sister is being cheeky asking for it back and also she’s got enough on her plate settling back in to job/ UK etc without the added responsibility of looking after a dog.
I think it’s wrong for family to put pressure on you. Why should your family be put out for her mistake.

Have I stumbled into a parallel universe where people actually put the needs of a dog over those of children who have been through some enormous life changes? I say that as a dog owner by the way.
Your sister and her family moved abroad (huge life change) then her marriage broke down (huge life change) then she moved back with her children to start life as a single parent (enormous life change). I find it odd that you say it's 'emotional manipulation' to think of the needs of her children.
You took the dog on the basis she was moving abroad permenantly (3 years is a permenant move) but that has not happenened therefore she should be allowed the chance to have her dog back and her children should have the small comfort of having their pet dog around at a difficult time in their lives.
When I adopted my dog, the refuge considered it to be a trial for the first 6 months as it's only then that dogs might have settled (in our case, it was much much longer). You've only had the dog 7 months, it won't have properly settled yet.
Just explain the situation to your kids - think of it as a great life lesson in being adaptable and putting others needs before your own and get a new dog/puppy in a few months' time.
Meanwhile maybe support your sister through a difficult time.

You have two dogs. You didn't want a second dog. You are totally within your rights to keep him but is it really worth wrecking your wider family relationships for?

In this situation it would be quite possible to act like a grown up, be disappointed and understand that your kids are too, but support them to deal with it. The dog will be fine. He settled with you and he will settle with her.

I was just listening to a podcast about what people regret when they are old, and it is often falling out with family over what, in retrospect, are quite small issues. I honestly think it would be a mistake to alienate your wider family over this.

I don’t think being ‘fine’ is enough when it means he’ll be left alone more. The dogs quality of life will go from excellent to much poorer if he goes back due to my sister working and being busy with the kids activities, doing it all by herself.

I remember being devastated when my grandparents collected their dog after they'd been away for months.
We moved on very quickly.

I think your sister has lost enough, can't imagine denying my sister the dog she paid for in that situation.
You could try offering to buy her another dog, but I suspect the dog would be happier going back with them. My grandparents' one was thrilled to see them.

honeylulu · 04/09/2026 10:45

I had mixed feelings about this issue until I read the follow up post that indicates that the dog seems to prefer your family, to the extent he doesn't want your sister to even walk him without one of you there.

I think doggo has chosen his family!

You haven’t read the thread.

Yes, I have. Just because the dog wanted to carry on playing on the occasion your sister visited doesn’t mean its bond isn’t with them.

You don’t want to read the truth IMO. Keeping her dog is cruel. If you want to do a staggered handover because you think that would be better, then that’s fine, but you seem to be determined to keep a dog that’s not yours just because you have a bit of paper saying you’re the owner. Morally you’re not.

Put yourself in her shoes. How would you feel to lose your own dog and have someone refuse to hand it back?

Anonbakerylady · 04/09/2026 10:38

Run that by me again? You don't need a husband to look after a dog. If anything, now she has dropped the DH she may have more headspace for the dog.

In my personal experience, itss much harder to give a dog a good life if you are the only adult in the house and have been used to there being two of you....been there done that when I was widowed and I had no kids to be responsible for and the dogs were much older so needed less exercise.

WhisperingHi · 04/09/2026 10:36

Here we are. This is your real reasoning. You didn’t agree with her moving and now it’s backfired for her, you’re looking to make a point.

She and her kids had dog for 42 months. Versus your 7 months.

You want to keep her dog regardless. It’s telling that the rest of the family support her in having it back.

Your sister is going through a VERY difficult time, and your response is “well you signed it over so it’s mine!”.

Rather than what a good sister would do, which would probably be more like “get yourself settled and if you guys would still like it back, that’s fine. We’ll really miss it, and we feel it’s already part of our family, but I appreciate you must feel this even stronger having had her from a puppy. I hope you’re alright sis, I know what struggle this must be for you”.

Kicking your sister when she’s down is a low blow.

If you read my posts you will see you are wrong.

My sister is currently living somewhere as a single mum with hardly any support. She needs to work and that will mean leaving the dog alone. How is that better for the dog? She is likely going to need to increase her hours so the dog will be left more.

She has seen the dog 3 times and the dog has not wanted to be with them. The dog is attached to us and bonded to our other dog.

Adding a dog into her difficulties isn’t the answer.

As a family, we have asked her to move near us so we can support her. We have offered to have the children after school and whenever she needs to work or wants a break. The children can see the dog then.

I think the circumstances into which the dog will be returned make keeping him the obvious option. He has company, is regularly walked, has his medical needs attended to promptly and is a family dog. What he will be returned to is a life where he will spend most of his day alone aside from a dog walker, and there will be a different dynamic as Dsis is now a single parent. She essentially gave the dog away when they moved, the ownership details have been changed, he’s had veterinary treatment that Dsis neglected - all at OP’s expense. I think it’s really cheeky to ask for him back as though nothing happened.

bridgetreilly · 04/09/2026 09:02

After seven months, a dog has learned to feel secure in its new home and it is very unfair and unkind to move it again.

This and ownership was transferred. Also what about your DC getting upset? Your sister should look to re-home another dog if she wants one. Your niece and nephew can still visit your dog.

BeardySchnauzer · 04/09/2026 10:42

It must be very hard for your sister having such a saint to live up to🙄

tinyspiny · 04/09/2026 10:39

The dog should stay where he is as it’s his best interests to do so . With @WatchTheStormTouchDown he is rarely left and has got used to living with another dog so it would be a detrimental move for him . Plus if the Ops sisters family were that bothered about the dog then they would have taken him with them when they moved . There is no way I would have moved abroad and left my late dog behind , he was a family member . The OPs sister is treating the dog like some kind of toy that you can just pick up and drop when it takes your fancy .

Sleepdeprivedandcaffinated · 04/09/2026 10:39

While he undoubtedly remembers them, it will be difficult for a dog with free run of a large garden, constant human companionship, and another dog to play with, to go to being alone for much of the week.
Especially losing out on your other dog. Bonded dogs can be miserable without each other to play with. Fine, but not happy.

Giving him back is the nice thing to do for your sister but it isn’t necessarily the right thing for the dog. Keep him. As difficult as it is for her, she gave him away when it suited her. He’s not a comfort blanket to have back because she’s having a hard time when he has a happy and established life with you now.

sugarplumlily · 04/09/2026 10:31

Also - if she’s now a single parent the dog will
likely not get its needs fully met. I imagine your sister needs less expenses, more time to organise and parent her kids alone, and time to work/find a job. It’s very hard to fit a dog into that when you are newly split and working life out again.

Run that by me again? You don't need a husband to look after a dog. If anything, now she has dropped the DH she may have more headspace for the dog.

Personally I would give an ultimatum that if they take the dog back it will be on the understanding that you will never speak to them again as it will break your kids hearts.

And this kind of overreaction is why so many Mners struggle with relationships and friendships. Why on earth would the OP do this? She'd be losing both her dog and her relationship with her sister and her sister's children!

BreatheAndFocus · 04/09/2026 10:35

How can you not give him back? I’d be devastated if that was my dog (poodle owner) They’ve only been gone a few months! If you’d taken in what you thought was a stray and then his owners tracked him down, would you refuse to give him back because your children liked him?

The dog’s bond is still with its original family. You can get your family a dog if you want one. Don’t take your sister’s. IMO it’s cruel - both to her and her family and to the dog who will be ecstatic to see them.

He is our dog.

It isn’t my fault that the decisions my sister makes don’t prioritise her children and dog. We make decisions that’s are best for our children and dogs, always have and always will.

Here we are. This is your real reasoning. You didn’t agree with her moving and now it’s backfired for her, you’re looking to make a point.

You could be the bigger person here? You are technically ‘in the right’ but come on. Is this really just about the dog, but about history and dynamics between you and your sister? Only you know the answer to that.

We have always had a great relationship. I didn’t agree that her moving was a good idea , neither did family and friends, but it was her choice. Our parents are desperate to make things better for her, as am I, but we differ on what doing that is and it’s causing a problem.

The dog has a better quality of life with us. If he goes back, he will be on his own when my sister works other than a dog walker coming in for a 30 minute walk. Here he has constant company of humans and another dog, more walks and exercise etc.

He is a Standard Poodle. They had him from a puppy to 3 and an half and he’s just had his 4th birthday with us.

Anonbakerylady · 04/09/2026 10:34

You sound very judgemental of your sister and her decisions. She made a mistake but you do not know what kind of pressure she was under by her now ex husbad. It must have taken enormous courage to admit the move was a bad idea and bring her DCs home.

You have only had the dog for 7 months. Imagine what comfort the dog would bring to your sister, as a single mum it would be good for her to have someone to sit with in the once her DCs have gone to bed. I don't know what the situation is with thier father but if he has contact it could be lonely being without her DCs. Your kids will be upset, but they have another dog and they have thier parents, they haven't been through what your niece and nephew have been through, this would be a good lesson in compassion. Plus it sounds like if you keep the dog you will permanently fracture your family's relationship with your wider family which is going to impact your DCs.

ThreadGuardDog · 04/09/2026 10:34

OP are you absolutely sure that there’s no chance of a reconciliation between your sister and her husband, which would result in them leaving again. Because that really wouldn’t be fair on the dog, or anyone else for that matter.

WildCats24 · 04/09/2026 10:33

WatchTheStormTouchDown · 04/09/2026 10:16

I can only go on what I’ve seen on the 3 visits she has made. He really wasn’t very fussed with them. If I thought he would be happier with them, I would consider him going back as upsetting as it would be. I firmly believe he is happier with us and has a better quality of life having more company, more walks, another dog, rarely being left with is working from home etc. We have also paid for an issue with his eye that my sister had left, he gets groomed more regularly etc.

The neglect on the eye issue is the nail
in the coffin for me. Keep him.

godmum56 · 04/09/2026 10:31

have you read the OP's post about how the dog behaved when it saw the sister again?

Perhaps the OP’s sibling could prioritise her relationship with the OP by not asking for the dog back and causing a whole heap of stress.
And be grown up enough to explain to the children that no, they cannot have dog back but they can get a new one instead.

Sorry quoted incorrectly !
