     Reading to dogs is an unusual way to help children improve their literacy skills.  With their shining

brown eyes, wagging tails, and unconditional love, dogs can provide the nonjudgmental listeners needed

for a beginning reader to gain confidence, according to Intermountain Therapy Animals (ITA) in Salt

Lake City.  The group says it is the first program in the country to use dogs to help develop literacy in

children, with the introduction of Reading Edueation Assistance Dogs(READ).  

    The Salt Lake City Public Library is sold on the idea.  "Literacy specialists admit that children who

read below the level of their fellow pupils are often afraid of reading aloud in a group, often have lower

self-respect, and regard reading as a headache," said Lisa Myron, manager of the children's department.  

    Last November, the two groups started "Dog Day Afternoon" in the children's department of the main

library.  About 25 children attended each of the four Saturday-afternoon classes, reading for half an

hour.  Those who attended three of the four classes received a "pawgraphed" book at the last class.  

    The program was so successful that the library plans to repeat it in April, according to Dana

Thumpowsky, public relations manager.
