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.

Well how do you see family dynamics going forward if you don't give the dog back? It's going to be incredibly awkward and I don't think your sister or niece and nephew will forgive you.

I totally understand why you would want to keep him and he is yours legally but for the sake of family piece I think I would give him back. Totally horrible situation with no winners but be the bigger person and if she is now single she may realise that she can't actually keep the dog

RigsbysCat · 04/09/2026 10:21

OP I think anyone reasonable looking at the full circumstances, including your updates, would conclude that the dog is obviously better off with you.

I get that your sister and her kids have had a rough time, but this is surely about what is in the dog's best interests? Animals don't exist for the convenience of humans. I actually think your sister is being selfish and bang out of order in asking you to return him to her, especially as the dog himself appears to have moved on emotionally. You are doing the right thing by the dog and to me that's what's most important

FFS, it’s her dog. Her kids have only been without it 7 months.

Your sister is going through an international move and a divorce, and you can’t give her back her dog?

YABU and a bad sister. Things change, your kids will understand, just like hers had to when they left.

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.

You should give him back.

Firstly, for the dog - he’ll be more closely bonded to your sister and kids having been with them 3.5 years from a puppy.

Secondly, for your sister and kids - they’ve been through a lot and lost their husband/dad. Give them their dog back!

One of the other options they were considering for him when they moved was some sort of a dog share among 3 sets of friends where one set had him for 2 weeks and then he would go to the next lot of friends. She’d didn’t do it but she did consider it, so I’m very justified in my comments about passing him around like a toy.

She actually would have done this????? FFS KEEP THE DOG

He has seen them 3 times. The first time he was a little excited for a minute and then went back to lie on the sofa with our other dog. The second time he stayed in the garden and wouldn’t go to her when she called him as he was playing with my son and other dog. The third time she tried to take him on a walk and he wouldn’t leave the house without my husband. 😞

If he had seemed to want to be with them, we would have been more likely to think more about it but he didn’t.

The dog has made its feelings clear. They can get a new dog. You might end up with that one too

Cloudtime · 04/09/2026 10:18

Based solely on your comment about where he seems to be happier , I’d keep him with you.
If you were unsure about which environment he prefers or he had reacted differently to your sister , I might say differently.
it’s a really difficult situation , I see both sides but I think the dog gets to decide !

@Springtimeinsunshine it's not that simple.

We see a lot of people take pets overseas only to have to send them home again as they can't cope with i.e. the change in temperature.

Plus, if your housing situation was changing (I.e you lived in a house before and had to move into a flat) thats another good reason not to take a dog - how is it fair to put a dog that has only ever known a garden into a small flat?

Then you have all the stress of packing, changing countries, registering children in school, getting situated in work (which originally will be very long hours because of wanting to make a good impression), sorting out relevant dog care/walkers etc. Sorting out even basic things like furniture, getting unpacked etc. Those things can take months. It's not as simply as 'take the dog with you.' And even if it was, very often the dog is much better staying where it knows with people who can help.

It's very easy to be judgmental, but taking a dog overseas when you're changing jobs is really not that simple and until you've done it or actually helped someone do it...it's really not something you can begin to understand the complexity of.

I have done all this including returning early and having to put the dog in quarantine. I still say that the OP should keep the dog. Her sister agreed to the terms and its not like the dog hasn't settled or is having an awful life. I suspect that the sister is having a bit of a knee jerk reaction to the family break up and it will add to her her responsibilities in a way that will not benefit her life or the dog's.

Genevieva · 04/09/2026 10:18

She should get a smaller poodle that better suits her new life.

WatchTheStormTouchDown · 04/09/2026 10:16

WhisperingHi · 04/09/2026 10:09

But you would say that. You’re biased and seemingly intent on keeping it. I’d be very surprised if a dog wouldn’t recognise your sister as its primary owner with them having had it since puppy, and you only since February. As much as you’ll deny it.

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.

No, she considered it before we had given any answer. She had a few options on the table. Please stop making things up to suit the narrative you have decided on.

She considered it but ultimately didn’t go ahead with it. It doesn’t fit with your view that she wants to pass her dog round like a toy - people consider many things in life. You really don’t like your sister, do you?

RecyclingSal · 04/09/2026 10:15

Don't give the dog back, @WatchTheStormTouchDown. He sounds so very happy and settled and not only could it cause distress to the dog, but also to your other dog and children. I totally agree with you 100%. Yes it is sad that your sister's plans did not go as she expected, but that's not your fault, or the dog's fault. He is yours now if she transferred ownership etc. I'm sure Judge Judy would back you up here also 😉

Contain4 · 04/09/2026 10:13

In theory I would want to give the dog back for the kids sake - they’ve had to get rid of their beloved dog, leave their school, leave their home, leave their country, move to a completely new home, country and school and now their mum and dad have separated and they’ve had to do all move back - all within a few months.

That’s incredibly difficult for anyone to cope with and I completely understand why your sister has focused on telling them that at least they’ll get their dog back.

However it sounds as though your sister will find it challenging to have the dog back and she’s going to make her life harder because she wants her kids to be happy.

How far away do you live?
Could you speak to her and say how she’s going to make more work for herself etc.
I would encourage her to have the kids take the dog back to theirs on a regular basis and walk it and play with it etc but not have it permanently.

That way you pay for everything, have none of the worry and they get all the fun.

I don’t think that’s true. We’ve lived all over. People can and do bring dogs. They should have thought about this before they made the call to abandon the dog in the first place.

Mamamiacanisitthisoneout · 04/09/2026 10:09

I think you should keep the dog. Whilst the dog was still very young your sister chose a life that was incompatible with owning a dog. So it seems likely that should the dog be returned to your sister, it will happen again. And as you would be less inclined to agree to looking after the dog next time, it may be passed to anyone it can be palmed off on. If you can commit to it properly for it's lifetime you should keep the dog settled with you.

TemporarilyCantDoMyself · 04/09/2026 10:07

I've read all your posts @WatchTheStormTouchDown , no contest, the dog is your dog. Honestly I can't think why anyone would, if they're looking at the dog's best interests, disagree.
Please keep ddog. And please consider posting a wee pic of ddog. 😂

zurigo · 04/09/2026 10:07

I am nice and I would never treat my DSis the way you're treating yours. But fine, you've clearly made your decision and were hoping that this thread would be a parade of people telling you to keep the dog, which you'd already decided to do, so you could pat yourself smugly on the back. So great, you crack on, but accept that you're choosing this dog over your DSis and that she and the wider family aren't going to forget that easily.

Do you not think that it would be heartless moving the dog now when he has the companionship of another dog being in the house and enjoys that companionship. Do you really think it fair to remove the dog from that companionship and have him return to a set-up where he is by himself for a large part of the week. No fellow dog for companionship/no humans.

Like I said, it depends if the OP cares more about the dog or her sister. The dog lived with her sister perfectly happily for years so I don't think it is a major problem to send it back. Her sister and her children have gone through a move and a marriage break up. It could be seen as a little heartless to keep the dog.

Sorry I missed that one. I think let the dog decide - and he appears to have chosen you!
