Collecting A Security Deposit for A Service Dog

[Erika Banks]

I've got a landlording question -- I have a tenant that has a child requiring a service dog.  The tenant has purchased a puppy and registered the dog as a Service Animal.  I understand I am limited to two questions I can ask :

(1) is the dog a service animal required because of a disability, and 

(2) what work or task has the dog been trained to perform.)

However, the puppy isn't potty trained.  Am I able to collect a security deposit or request that the dog be potty trained before entry? Want to make sure I abide by laws, but also protect the property....

Thank you in advance for the assistance.
