Breed rescues are the number one source for good adult Chihuahuas. If you can't adopt a Chi, please consider volunteering and/or making a donation to a local, regional, or national rescue. If you can drive dogs to the veterinarian, pick up donated food, collect dog-food coupons, or provide a specialized service, such as Web site design or legal services, your generous help will be greatly appreciated. Short on time? Think about stroking a check to your favorite rescue: Chihuahua rescues are always in need of cash to help defray veterinary bills, pay for food, and keep supplies on hand as dogs come in to their foster programs.
