Unless you laterally transfer dogs (which is a dangerous practice, and I urge you to read more about it in the "Minimizing Risk" section), you will need a place for them to stay. This section discusses some of the options available, with minimal expense.
Also, if you have other pets, you will want to have the rescue checked by a Vet before exposing your own animals to an unknown element. Parvo would be my primary concern, with certain strains of worms, and kennel cough also being a worry. Be safe first, and minimize the risk.
Rehabilitating a rescued dog inside your home provides direct contact with the animal, and helps it get a feeling of security quicker. It's probably the best method, but it's up to you to protect your things as well as the dog itself. Common sense should tell you what is right.
Also, how about shrubberies and plants? Do you have anything in your yard that may be toxic to dogs? How about the yard treatment program? Take a good look around, and be safe. When in doubt, contact the experts for your Breed.
