The best option is go online and register open the account and a link no kill and post your scenario that you need help to find he or she a home.
Dallas animal services or Dallas SPCA or contact a second chance rescue and see what availability they may have, also check in to no kill shelters as Dallas is overloaded and dogs aren't lasting too long before euthanized.
You can drop off at the "intake" side of the shelter.
