Can our landlord force us to remove our service dog

Your lease will most likely control whether or not you can have a service dog in the apartment. You may be able to argue that a reasonable accommodation be made for your circumstance. Without further information, it is hard to answer this question. I suggest you find a local attorney for a consultation. Many times this is free.

There seem to be some glaring misconceptions regarding service dogs and legal issues regarding dog bite law in the statement that you have given. The first is whether or not you actually have a service dog. I don't understand how you can have "a service dog that moved in with (us) to our current residence." Is it your service dog? Does it provide services to you for a disability? Has it been trained to do so? Is it an emotional support animal? Most service dogs are trained and would not be leary of strangers, thus would not require warning signs. Even if your dog is a service dog or an emotional support animal it has bitten someone. Your landlord's argument is that your dog is a direct threat to the health and safety of others which is an exception under the ADA. Additionally, a landlord is only required to provide a reasonable accommodation under the FHA. The landlord's argument is that when a dog bites someone, it is no longer reasonable to accommodate you with a biting service dog or support animal. Your argument is that your dog was provoked and it was due to negligence of the parents and children. If you have renters insurance, you may want to contact them, as you still may face civil liability for the children injuries. I suggest that you contact an attorney in your area to combat your landlord's attempt to evict you. It does seem as though you made concerted efforts to warn individuals about your dog.

Yes, they can deny the service dog accommodation if it bit someone.
