Before anything, I do like animals, but I do not love them as some people do. I've had many family pets growing up, but would never be able to say I cried when any of them passed away. I just don't get emotionally attached to animals.

With that said here's how the dog came into our lives: Ex-wife adopted a dog shortly after our divorce. I was HIGHLY against it. She had previously adopted a cat that she couldn't take care of, so I told her this was an even worse idea. She then adopted an 85 pound American Bulldog and Pitbull mix.

Fast forward about six months, and she is saying she's getting rid of the dog. I didn't care, and I told her it didn't matter to me. She then asked if I'd take him, because she doesn't want him put down. He's a six year old, huge dog that barks all day. I still said no. I had no means to take care of him. So she called my dad, who I live with. He can't say no to anything related with animals, and so now the dog lives here. I told my dad that I wanted nothing to do with the dog, and it's 100% his responsibility. Of course that didn't happen. At least three times a week, my dad will leave for the entire day, and ask me to go home on my lunch break to take the dog outside, or if I'm not working, to take him on walks. The answer is always no. I am usually gone on my days off, and not revolving my days around a dog I did not want. Recently, it's escalated to my dad being home and asking me to take the dog out because he's too tired to do so, or to give the dog a bath in my shower because I have a better shower head. He's also a huge germophobe, so he will leave shit in the yard, and ask me to pick it up for him. This last one is what lead to me telling my dad that if he can't take care of the dog, he needs to suck it up and get rid of it. My dad said I'm just an asshole and should help take care of the dog because he's a good boy. This last week, I've done absolutely zero to help, and my dad is now pissed that he has to do this all himself, and says I'm an asshole. So AITA?

TLDR: Dad took in my ex wife's dog, and I don't want to help him care for it.
