It?s final exams week, and that means it?s time to send in the hounds. UW-Madison students will have a chance to relieve test stress by petting and hugging therapy dogs at Helen C. White Library Tuesday from 3 to 7 p.m. Dogs on Call, Inc. will bring more than 20 pooches into the library – from Shih Tzus to German Shepherds. This is the event?s third year.
