Want to actually MEET an AHT? The American Hairless Terrier Association has recently launched an interactive allergy test map that will help you find the nearest owner or breeder that is willing to let you meet their AHT. It's a great way to find out of this is the breed for you! Check the map out at http://www.ahrtc.com/AHTmap.htm
What you will need:
Place T-shirt in baggie and mail all the above to the breeder who will in turn have a hairless terrier sleep with the T shirt.
If you have any concerns about the accuracy of this test. Place a 2nd T shirt with Ziploc™ type bag in the envelope as well as a 2nd self addressed and stamped mailer in the express mailer. The breeder will then also have a T shirt to place with a coated dog.
When you get them back. Wear the T that has been exposed to the hairless
dog first. If no reaction ensues.... wear the 2nd T shirt. Should you
have a reaction to it... you will know the test worked and you CAN tolerate
this breed of dog. :)
