It's called an easement by prescription. 

I've rented to more than one that were abusing prescription meds.

The verse you mentioned in your original post (borrower slave to lender) is a Description verse versus a Prescription verse.

they are disability assistance animals that are differentiated from pets by having been prescribed/recommended by a licensed healthcare professional (ie, physician or pscychologist/therapist).enter pet therapists. they might prescribe a pet (or petS) for xyz reasons. but the moment the pet is prescribed/recommended it seems a pet obtained or used for that purpose transforms into a support animal, and is protected under provisions of the ADA.with service and support animals, proof of need is required (especially in NO PET policy units/buildings) in order to document that we are not discriminating against any other tenant(s) that may want to have an animal as a pet (as opposed to as a service or suport animal).enter the likelihood that we will likely be given a prescription or recommendation letter that at bare minimum will indicate the tenant has some sort of disability, plus may or may not share what physical, health and/or psychological condition(s) the animal was indicated for, or in the case of more than one support animal, which symptom each pet assists with.a predicament?
