You already asked this question - and the answer remains, yes, the landlord can charge you a deposit for a companion animal. Whether your landlord could later ask you to move out - no one can answer that without seeing a copy of your lease. You should speak with a local attorney for further guidance.
Yes - as discussed in your prior question, they can charge you a deposit. Yes, depending on the lease they can ask you to move out - but it really depends on the lease.
Take your lease to an attorney or legal aid to review. Also, it's not a companion dog until certified a companion dog/service dog.
Good luck with your situation and I'm sorry you've reached a point where you need the assistance of a companion, but at least dogs can be great companions and friends.
Please see the answers you got to your previous 2 postings,
which are the same - yes you can be charged a pet deposit even for your prescribed companion dog, and whether your landlord will retaliate against you cannot be known and isn't something you should worry about.
