Is AUTHOR wrong in the post ? POST : So backstory: I moved into this apartment 2 months ago with my roommate. I brought along my dog and I paid $250 in deposit money for her (which is required by our landlord for each animal). 3 weeks ago, my roommate decided he also wanted a dog and brought one home. But he doesn’t plan to register the dog with the landlord or pay the pet deposit. 

I know money is tight for him because of the new dog so I was hoping we could just split the pet deposit money so that I don’t have to basically pay for damages possibly caused by both dogs. Also, his dog is a puppy and is constantly having accidents in the house while my dog is a completely trained adult dog so I just feel like it’s unfair. 

Well I brought this up and he made it seem like I just want him to pay for possible damages my dog might have made in the first 2 months that she was here before his dog. He said that it doesn’t make sense for him to pay half since the deposit is registered under my dog and not his. 

So AITA for asking for this money?
