Two arrangements may suit a dog that cannot be near other dogs. With private home boarding, ask about other animals and shared spaces. With in-home overnight sitting, the sitter stays at your house and your dog keeps its familiar territory.
In Austin the choice often comes down to the car and the heat. If your dog travels badly, or if the only comfortable loading hours are before sunrise, a sitter at your place removes both the journey and the handover. If your home is the trigger-heavy part (a dog behind the fence next door or a busy street door), a quiet property further out is usually the better week.
If your dog has been turned away as aggressive rather than reactive, the requirement does not change, but be blunt about the history: bite record, what triggered it, how the dog was handled afterwards. Hosts who take these dogs want the full picture, and the ones who flinch at the question were never the right fit.
