This!
Look, the OP has bitten off more than she can chew, had a big dog in a small place, had a kiddie, got out of her depth, found herself in a situation she couldn't cope with, and something had to give. And it wasn't going to be her fecking BABY was it. FFS! Sometimes shit just fucking happens!
She is not a bad person, it's just one of those things.
We have a rescue cat, and we are her fifth home. (Original owner, Cats Protection, then 2 others who couldn't cope, then us.) She was a nervous kitty, and used to shit over the floor (runny poo) as she was nervous and anxious... She just needed someone very patient and tolerant to put up with the poo for a bit until her nerves settled down.
She was abandoned you see, dumped in an Asda Bag For Life at 5-6 months old, (on the side of the road,) then picked up by a passer by who took her to Cats Protection. They found an owner who was chuffed to have a lovely shy affectionate cat, but they couldn't tolerate the runny poos, and after 3-4 weeks they took her back. A few weeks later, they found a new owner. Same thing happened. Poor baby was sent back after 2 weeks then.
Then when she was around 9-10 months old, we saw her advertised on the website, 'looking for a home,' and we went to see her, and fell in love with her. Cats Protection said we can return her if we can't cope (told us about her issues, and her history.) She got so much love and cuddles and affection from us (and our 2 then young teen DC,) and yes, she pooed a few runny poos a few times on the kitchen floor, but after a week it stopped. A week! The other 2 places she had been at for 3-4 weeks and hasn't stopped. So her nerves and anxiety settled much quicker with us.
Long story short, SHE had been shifted about because of being abandoned, (and because of the 2 people who couldn't cope,) and she settled with us very quickly Still here now, 13 years later! Loving, soft, affectionate, little fluffball she is, and we adore her. 😍
tl;dr, there is nothing wrong with admitting you can't cope, and rehoming a pet. SHIT HAPPENS. LIFE HAPPENS. And at least the OP didn't abandon the dog.
Some people need to get a fucking grip, seriously!!!
