My parents killed the dog

My "family" dog (was a gift for my mom) passed away in February it was very heartbreaking because I wasn't able to say goodbye and couldn't get to see her (was at college 2 hrs away from home). Apparently she died from a hormonal problem witch caused her a lot of pain, even after the surgery was a successful her body couldn't handle it. In the mist of me crying on the phone with my mom she tells me "we didn't know what was wrong with her. She was sick Monday so we made her soup and the next day she was fine".

Before I left home I noticed she has been acting off, peeing a lot, throwing up, and more. I admittedly told my parents about it and they shrugged it off. They said "it's because she's old" she was 6 years old. I told them she needs to see a vet something not right, I looked up her symptoms and it could be life threatening. Again they did nothing but made her soup, got mad when she had to pee constantly and yell at her when she would throw up in her cage. It was so bad that she would hide the throw up so they won't yell at her.

I begged my mom to take her to the vet, I told her I would pay for it if it's too much. Come to find out she was behind on her shots and they were "to busy to deal with it". I don't have a car, I don't have any medical records to get her shots and she's getting worse. I cried and prayed she'll be okay. Finally my mom said they'll make an appointment with the vet, which was a lie.

There was never an appointment, she never got her shots, she didn't even get her nails clipped. I was always the one giving her a bath, feeding her, giving her a walk, brushing her teeth, staying up with her when she was sick. While all they did was take pictures of her and the caption would be "she's so beautiful". She was a female yorkie. I also found out the day she died that they went to 3 different hospitals because "it was too much money" it was 450....that's the same amount they pay when they go shopping.

Fast forward today I'm still heart broken about because I should've done better. She shouldn't have to die like that, suffering because of them. I hate I didn't do more. They're thinking about getting another dog...and I'm scared they might do it. If they do I won't let that happen again, even if I have to take the dog with me when I move out I will.

I miss you so much and I'm so sorry.
