Service, assistance and emotional support animals are not technically pets and owners do not have to pay pet fees. The landlord, however, can charge a security deposit and may still seek money from the tenant if there is any damage caused by the animal to the home. Also, if there is a nuisance issue the landlord does have the right to try to remove the animal through legal proceedings.
同时送了相关文件。现在好像是不能赶走房客，我能不能增加月租金$50（狗费）? 合法吗？坐标在Michigan. 先谢了。
可以养狗并不意味着不可以增加房租

开信的这个人是个混混。所有的州都哪一个license。她不是healthcare provider，没有权利开残废证明。这个狗证也是无效的，任何人可以开一个网站注册狗，说明不了什么问题。
你可以要求你的房客开一个医生证明，证明有disability，否则你可以同意收狗，但是要交pet fee 和 pet deposit。
否则就追究到底，反正不能让她赚你便宜。
