Boarding for reactive dogs?

Does anyone know of a boarding facility that can take reactive dogs in the Houston area? Both of my dogs have been in a boarding facility in Spring, TX but it was many years ago. I'm not sure how they will react now. I will not be able to take them to that facility because it's far from where I live now. I have two elderly dogs that do not like being around other dogs or people. They growl and bark at people and other animals.
