Who should pay for the dog?

[JollyGreenLemur]

So my mum bought a dog 7 years ago and she already had a dog, her other dog then had an operation on his leg and couldn't play so I put in 2 weeks holiday at work to have her new dog at my house while the other 1 rested, this turned into 6 or 8 weeks then she had her new dog back, I paid for her new dog some training as she wasn't good on a lead (part spaniel) and took her out for walks.
A few years later her other dog then got cancer and maxed her pet insurance and my mum doesnt work so i paid for her "New" dogs dog food, pet insurance, vet bills and for her to go to the groomers, I didn't mind as she didn't have the money and I was in full time work with my bills and mortgage getting paid without struggling.
Now I have 2 kids, a toddler and a baby, im on maternity while January, my partner is in full time work but we are having to be very careful with our money especially as I won't get any money the last 3 months of my maternity, my mum still doesnt work and shes waiting for her pension which I think she gets next year, her other dog has now died and she refers to this dog as a shared dog, I pay and she has her kind of share.
Aibu to stop paying for this dog?

You’re being unreasonable for continuing to fund your mum’s pet for ages!

How is your relationship with your mum generally? Just wondering if this is a single blind spot she has or if this is one of those tip of the iceberg situations?

Agree with other posters who have said to follow up and state you can no longer pay these expenses x

Now just don't pay for anything. And when she asks say "I told you I couldn't afford it any more mum, it's not my dog."

You’re enabling your mums laziness…

Stop paying.

It's not great if im honest, we've never really got on but the other issues I have I can live with, i think i just have contact because shes my mum and now for the kids, I think after her dog died I kept paying as I was just used to doing it but recently I've been watching what I've been spending and I took her to the vets about a month ago and she said there was a prescription and it would only be a couple of pound, I went in and it was £80, this stopped me going in matalan and now shes wanting to go back to the vets and she will be wanting food soon and looking at my mum I don't think shes struggling, I just wanted to make sure I was in the right stopping it before I said no

Just explain to her your situation.

She may not take it in the first time, or see it as just this time you can't help, but help will resume.
You are going to need to keep it clear, simple and repeat as needed.
"Mum, I've told you I can't support your dog anymore. You will have to take responsibility for your dog"

If she doesn’t work what is she living on? If she’s on benefits she would be able to use the PDSA wouldn’t she? At least that will take care of vets bills and I would tell her she’s got to pay for HER dogs food and other expenses from now on. If we could afford 2 dogs a few years back what’s changed now?

PDSA don't always have clinics in every town.

If you cant afford it you should stop

But she certainly does though.
Her reason is YOU.

Just stop being a pushover
You really don't need to explain anything to her.
Her dog, her problem.

PS: I am a dog owner. My dog, my responsibility.
