My parents care more about their dog than me

My husband and I moved in with my parents right after we got married because we wanted to look for houses in NC and since they live in NY and my husband’s family lives in California this seemed like a great idea. Besides the convenience, living with them has been awful. They’re disorganized, unclean, and stubborn as all hell. My mom is extremely selfish and has severe anxiety and depression that she wallows in. My dad is a good person but also ill tempered and extremely impatient. He gets pussy whipped by my mom somehow, which is why my childhood was hell. My mom was a shitty parent and my dad went along with it. I was also a glass child since my brother is autistic. Anyway, they got a new dog because they thought one wasn’t enough I guess. They adopted another mutt, female and about 2yrs. She never stops barking, chews up shoes, destroys the garbage, begs for food, jumps, terrorizes my other dog, and she even ran away on a walk when she got spooked, then was found a few hours later. She seems to have been nothing but a a burden to my family but because they are such “animal lovers” they still bend over backwards for this dog. She just got fixed and one night she was panting and restless, so they took her to the vet at midnight. She had a minor infection where the stitches were, probably from trying to itch herself on the dirty furniture that my mom never washes. Then I mentioned to my mom the time I had a chronic UTI at 5yrs old and how they refused to take me to a doctor because they said it was “in my head” so they let me suffer for an entire year before they believed me. But when the dog is uncomfortable they take her to the vet right away. It just irks me knowing how neglected I was by them as a child and to see them now as an adult shower this dog with love and attention.
