Military Vet w/Service Dog

[Benjamin Bubar]

What do you do when you have a 6 month lease we an Army Ranger Vet who has a service dog and his lease is expiring at the end of April.  Hes been great but has ignored by attempts to contact him about moving our or extending the lease.  The property has trash scattered outside and i'm afraid its going to affect my summer rentals.. How do I get him out effectively?
