HELP! I fed my dog cooked chicken bones and I'm worried of his health?

First, I am an idiot, and sorry for my English it’s not my language. My mom brought home some leftover chicken bones this Sunday night and I gave them to my dog, I did this because I know he loves chicken but I am too stupid to realise that cooked bones are not good for dogs!

My brother told me he puked all the bones the next day, later that day his poop was a bit chalky, so as the other poop he had on Tuesday which is more chalky than his previous poop which totally isn’t good. This was the time where he lost appetite. He didn’t eat plenty on Tuesday, just drank water.

Last night, I gave him rice with cooked chicken, (and now no bones, forever) ate half of it, and the other half this morning. Today he still won’t eat but I offered him raw chicken (no bones, still) and that’s the only thing he would eat. I also made him a pumpkin puree and let him take it using a 10ml syringe 3 times to help him poop.

He still hasn’t pooped yet and I think he’s constipated, I would bring him to the vet but my mother wouldn’t give me money as she doesn’t care about the dog I don’t know why she took him in the first place. I am so worried and I feel so bad for unknowingly doing this to my dog I love him and now I don’t know what to do I cannot take him to the vet and I don’t know what to do but worry. I have read some answers in an article where their dog died from eating cooked chicken bones and they make me so paranoid, what if my bones get stuck in my dog’s intestines and he dies? Has anyone encountered the same thing with their dogs? Please help me.
