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.

@WatchTheStormTouchDown what's best for the dog sounds like it would be staying with you.

What's best for your sister and her kids is having the dog back.

Perhaps the dog will trash her house out of boredom being left along during the day so she will end up seeing sense and having the dog return to live with you?

It's a really tricky situation. Your agreement of the dog staying with you was based on 3 years. It has only been 7 months.

Personally I would return the dog to her, but I would make her pay for the dog's board and lodgings for the last 7 months!

Sounds like your sister and her kids have had a shit time recently. Why would you not do anything you could to make that better? Give them their dog back.

Completely agree. It’s only been 7 months. Get your family another dog.

You might find the dog considers them to be his real family and would prefer to be back with them... you can usually tell. Our dog has spent summers at my parents if we've been travelling. He is very happy there, adores my mum in particular but he is wild with joy when we return

See my previous comment on that.

I think I’d give the dog back. It’s only been 7 months and your sister has had a split and had to move back home with her children. The children have also had to move and been separated from their dad so will be really unsettled. I think getting the dog back will help them a lot.
I understand your kids will be a bit upset but they’ve not had the upheaval their cousins have had.
It would be a really good thing to do on your part. It’s what I’d do if I were in your situation.
Maybe you could ask her for some money for the upkeep of the dog while you’ve had it and then put it towards a dog you choose yourselves.

Edited to add I just read you have a dog already. Give her the dog back. I think it might sour relations irreparably if you didn’t.

WatchTheStormTouchDown · 04/09/2026 10:00

@zurigo They could have chose to not move and keep their dog. I didn’t force them to do anything. Our family and her friends thought the move was a bad idea for her, giving up her career, for the children and for the dog being left behind.

We were not looking for another dog. Another one of our dogs had just died and we were grieving. My MIL had also just been diagnosed with cancer so the timing wasn’t great for having a new dog. We took him because we saw him as part of the family and didnt want him passed around or given to a rescue. We couldn’t face losing another dog as we had just lost one and so that is why we only agreed if it was permanent. My sisters husband also told my husband that he was hoping the move would actually be for longer.

You sound really nice.

Massive dripfeed that you have another dog! Give him back.

That’s even more of a reason not to give him back. The dog has become attached to this other dog. Is it fair to the dog to take that from him? No, it is not.

If you love the dog more than your sister, keep the dog. If you love your sister more than the dog, give the dog back. Bear in mind that, all going well, your sister will be around for most of your life and the dog won't be.

If the dog is the type that gets very attached then it would probably rather be with the original owner. If it isn't, then it won't mind where it lives.

Edited

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.

Howmanycatsistoomany · 04/09/2026 09:58

If the dog meant that much to her and her children why didn't she take it with her when she moved? Keep the dog, your sister is a flakey dog owner and the dog deserves better.

My sisters house and garden is smaller, but not small. Our garden is huge. My sister works 3 days and her plan would be to have a dog walker take him out for 30 minutes at lunchtime but he’d be on his own the rest of those days. She’d then also have to leave him to take the kids to activities etc. She is going to be busy as a single mum and doesn’t live near us or other family.

We work from home and our dog is rarely left but he’s happy and settled when left for a couple of hours as we have cameras set up to see him. We have another dog who he adores and they’re very happy together. The both get at least 2 walks a day and a game of fetch at lunchtime. They also go swimming etc.

Massive dripfeed that you have another dog! Give him back.

Cheesemonster45 · 04/09/2026 09:55

I'm trying to imagine being your sister. If it were my dog, and I'd had to give him up permanently, I would have done so with a clause saying could I and DC see DDog X times a week when I return?

Did she do that OP?

But she didn’t force them, the OP said family would take the dog but it would have to be permanent. She knew well her family would become attached to the dog and the dog would settle, which is why she set that condition. Her sister did not have to agree. She made the choice to move abroad, she made the choice not to bring the dog, she made the choice to give the dog permanent to her sister.

This dog now has the companionship of another dog which he enjoys - do you not think it would be very unfair and heartless to take that away from him ??

LarryForPrimeMinister · 04/09/2026 09:55

Your dog now, keep him. What's to say she doesnt up and move again in a years time? She's obviously not that invested in the dog to not bother to bring him with them.

Stopthattractor · 04/09/2026 09:52

I think you're completely within your rights to keep the dog.

However getting a dog through the puppy and adolescent years is a huge feat and creates a bond, at least on the human side, that is hard to fathom.

I understand why your sister desperately wants the dog back. This must be a time of huge crisis for her.

I left my saintly dog for six weeks once and the family who had her were overjoyed to experience having a dog but completely aware they'd been handed the result of five years of concentrated work and this was a very cushy way to have a dog.

Although you can keep the dog, I would bite the bullet and put in the work with a new puppy yourselves. I think you would find yourselves forming a new bond. And the dog would move back fine, they're right about that. I think you minimise the attachment they feel to suggest they're treating the dog like a toy.

Dogs don't live that long in the great scheme of things. Family ties, or the lack of them, are more long lived and significant in the great scheme of things.

I am speaking as a dog owner who gave their dog to their parents during my divorce and having a job that would not be conducive to having a dog (and not enough £ to pay a dog walker). My dog was settled with my parents very quickly and even if my circumstances now changed I wouldn’t ask for her back as this would be utterly confusing for her and my parents would be devastated! We visit and adore my dog but she has a new home now. Keep the dog. X

Keep the dog, lose your family x

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.

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.

What about your kids getting upset that their dog is being taken away from them? That's your dog you keep it.

Cheesemonster45 · 04/09/2026 09:51

Ouch, this is a tough one. I think the toughest dilemma I've ever seen on here.

I dont think you're being unreasonable. I do think your family is to put this pressure on you as a quick way of soothing sister while she is going through a lot. You had an agreement that the dog change of ownership would be permanent.

As a compromise, could you offer to help your sister in other ways while she gets back on her feet? E.g. childcare, her DC could help walk your dog, meal prep etc.

No decision like this should be rushed and personally I would give your sister time to adjust to her new life. Without a dog for now at least.

Just to say - before your post is promptly deleted and MNHQ put you on the naughty step - I tend to agree

Gossipswhattodo · 04/09/2026 09:50

Your sister is back in the UK now, what if you give the dog back and then , maybe ( don't know the circumstances obvs) she decides to give living abroad another go , what happens then ?

I took on a friend's dog when she her partner moved in and her partner was allergic to her DDog ( she was pressured tbh in hindsight) I only took DDog on on the understanding she was then "my" dog , they split up after 2 years sadly but she was true to her word and dog is still with me , though she takes DDog out for walks occasionally.

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.

And how old is the dog? And what breed? That's completely relevant here.

I disagree with others that after 7 months a dog will be 'secure' in it's new home. I've known dogs that after 5 years still react like puppies when they see their original owners (I rescue, so I see re-homing a lot).

But honestly, regardless, I would show some compassion. She's lost her husband. Her kids have lost a dog. And the dog is their family. There are often very good reasons (as the wife of a diplomat, I have a lot of empathy for your sisters circumstances) why people leave dogs behind i.e if the climate is not suitable for them. It doesn't mean we don't care.

In the minority here but agree with you and @Shellityhorn

Sister’s circumstances have changed - show some compassion. OP’s children may be upset but sister’s DC will be too, losing part of their extended family (father and dog). The fact that there’s no ‘legal obligation’ to return is sort of nearly here nor there

Followthesunshine · 04/09/2026 09:48

And what happens the next time she decides to move abroad and leave the dog behind? She chose a life abroad over her commitment to the dog. She then agreed to transfer ownership to you - she didn't have to do that, if the dog meant that much to her she should have stayed in the UK. She made a choice and choices have consequences. I think you are absolutely right to keep the dog.
