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

WatchTheStormTouchDown · 04/09/2026 08:58

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.

Dogs pick up on low mood, depression and chaos. Leave him where he is settled

Tinkalinkalink · 05/09/2026 09:44

Ops sister needs mental health intervention. Dog stays with you now he is settled. Cruel to the dog to uproot him again.

Other arrangements which OP has weaponised against her sister to paint her as an irresponsible dog owner! Her sister can't win. I agree that after 3 years it would be a lot to return the dog, but it's only been 7 months!

It does make her sister an irresponsible dog owner to ask someone to look after your dog for 3 years and expect the dog back at the end of it.

Cos some have made themselves look stupid so they want it gone. It was obvious early on that OPs sister wasn’t coping and that the dog was better off with the OP, but some people kept on insisting the dog should be returned.

I agree with this. Some posters have gone really OTT when insisting the dog was returned. Even when OP said her sister was really struggling to cope, they dug their heels in and still insisted the dog should go back when it was obvious that wasn’t appropriate. Some people completely lost it on the thread calling OP names and making up scenarios. It’s strange behaviour and I’m not sure what to make of it. Now some people are still trying to twist OPs update. They should look at their own bad behaviour rather than OPs, who clearly cares for her sister.

EmeraldShamrock000 · 05/09/2026 09:39

I would suggest a 50/50 custody arrangement for the dog, that way you always have a trusted dog dog sitter going on holidays, both families can enjoy the dog, it works with children, surely it can work with a dog. Double the love.

SouthLondonMum22 · 05/09/2026 09:35

Caring people don't ask their sister to temporarily care for their dog for THREE YEARS without offering to pay a penny and then expect the dog back at the end of it. OP was right to put her foot down and say it would have to be permanent because it wasn't fair to anyone otherwise (OP, her kids who have already lost a dog and the dog).

OP didn't force her though, other arrangements were available.

Caring people don’t out their sisters breakdown on the internet. Paint OP like a saint if you want. She might have done right by the dog, at a very basic level, but she has certainly never put her sister first from the say she forced her sister to hand over the dog ferment (even though her sister didn’t want to) to today where she needlessly told us all about her sisters breakdown.

The only reason OP has done so is to make more people support her initial decision. No one who loved their sister would have done what OP has this morning. It’s one thing to share struggles, it’s quite another to be quite so outing about a life that is not your own.

But by all means, carry on insulting people…

If you truly loved a dog you would not move it - again - from a loving home where it is settled and has human company all day PLUS a dog chum to a home where it would be left alone all day apart from a 1/2 hour dog walk.

That's not putting the dogs welfare and needs above your own.

I disagree. I don't believe this is about the dog's needs. I think it's about the OP and her sense of superiority and judgement about her sister. I think this is clear from the OP and the totally context of all the subsequent posts. I don't agree it would harm the dog to return it to its family where it was raised and lived the majority of its life. The dog has only been with them 7 months. OP has not suggested the dog was mistreated and I think it's a-ok to have a dog even as a single parent and if you work 3 days a week. There are plenty of ways to make it work and raise a happy dog.

AIBU is absolutely packed with very personal family issues/dilemma which would be very obvious if a family member read it. I'm not sure why this one is suddenly inappropriate.

Agree with this.

And if OP actually cared about her sister she absolutely would not be outing the state of her MH on the internet where it’s likely incredibly obvious to anyone who knows the family. People can spin OP as caring if they like, but caring relatives don’t air their siblings MH laundry to MN.

I read OP's updates, including this morning . It doesn't change my view. I'm putting it in the context of all her posts on this thread, where she has not once demonstrated any empathy for her sister (or niece/ nephew) or capacity to see the other side- only judgement and superiority.

For example, this post from yesterday:

"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."

I don't think we have a reliable narrator.

I am a dog person- my dog means the absolute world to me and I certainly do not think she's a toy.

Some people would probably like it deleted because even after OP made it very clear that she knew her sister wasn’t coping and it wasn’t in the best interests of the dog to be returned, they continued to insist the dog be returned. They now realise they were wrong and that they have made tits of themselves and would have put the dog at risk of further disruption, which 2/3 of us could see.

I’m not sure what your comment has to do with OP outing her sisters MH struggles to the internet? Or was it a dig at me? If so I stand by my first post on this thread which was based off the information provided on the OP and not the subsequent long, outing and really inappropriate follow up.

needastrongone · 05/09/2026 09:05

Even the last post from this morning? OP’s poor sister is struggling very badly with her MH, to the point where it wasn’t deemed appropriate to leave her alone? This is and should be the priority.

That’s incredibly sad.

But this is also incredibly outing now. I’d think about removing it. If you care about your sister you probably don’t want to be splashing her MH crisis over the internet where it might hit things like the Daily Mail or even get back to her via friends or have your family see.

Well then you clearly are not a dog person. They are not toys. Dog is settled and didn’t want to know the sister on the 3 times she has visited.

needastrongone · 05/09/2026 08:54

Have you read the OP’s updates @Lacksie, particularly the latest one?

SaySomethingMan · 05/09/2026 08:53

ShitFacedShakespeare · 04/09/2026 09:40

I think you're right not to give the dog back as it will have settled with you and your DC.

However, I think this bit is totally unfair....

"He isn’t a toy to be passed around when people change their minds and plans change"

She doesn't think he's a toy to be passed around. For goodness sake have some empathy for her and her DC.

Agree with this

Lacksie · 05/09/2026 08:52

Packofsix · 05/09/2026 06:54

Honestly, the people saying give it back are clearly not dog people. You are right. Pets are not toys. The dog sounds settled and happy. No way in a gazillion years would I give it back and frankly I would be telling my sister how selfish she was to even suggest it. Draw a line under it, tell her you will not be discussing it anymore and then hopefully she moves on from it

My sister and children are at our house know. It came to crisis point yesterday evening with my sister’s ex calling me worried about her mental health after a conversation they had. I spoke to her and she asked for us to come and get the children as she said she couldn’t go on without her husband. Thankfully she agreed to come home with us too. Obviously I wouldn’t have left her in the state she’s in. We got home at about 2am with them so we are shattered but glad she is here as she needs support. She is saying she wants to go back to her husband and she has made a mistake coming back here. It’s a horrendous situation. The children are currently up already and happily playing with their toys.

Oh op, what a situation. She is all over the place isn’t she. What a mess. I hope you can all work through this together and she can make the right decision for everyone.

but even more important that you keep the dog- she is in no position to look after anyone at the moment and the status quo is best for all.

good luck op.

The dogs behaviour during her 3 visits to you were natural as it has a new routine - if it were with its original owners in their home it would slip back into its old routine - this didn’t constitute a fair assessment of it wanting to remain with you at all - as you would need to take it to her home but I think you have made up your mind as others have said - this isn’t about the dog it’s about how your relationship with your sibling is and how much you value salvaging it

Rubbish. The dog ignoring the sister shows that he doesn't miss his old life at all.

How could he slip back into his old routine when now the sister is going to be working 3 days a week leaving him alone and the dad is no longer there?
