CHICAGO，Illinois -- Students shouted，hugged and cried tears of joy recently as they played with certified therapy dogs （獲得認(rèn)證的治療犬） at Lane Tech College Prep，an activity designed as a break from the demands of preparing for final exams.
   This is the second year the dogs and volunteers have been brought into the school from Chicago-based Canine Therapy Corps to provide much-needed relief for stressed or anxious kids.
   "It's stressful around finals time，" Assistant Principal Sarah Hanly said，adding that this week students are turning in final projects，reviewing and studying for next week's exams.
   It seemed to do the trick.Shouts and cheers went up from a group of students as they met Waffles，an 85-pound dog，and rushed to put their hands on his fur.
   Junior Sophie Cohen sat next to Waffles，petting him and chatting with her friends and Waffles' owner.She said she had just been talking to her friend about how stressed out she was over finals. "Just the idea of having a dog in school is good because the school environment is just about stress，" she said. "And then here is this dog.You get a break."
   Monica Synecky，Waffles' owner and a volunteer with Canine Therapy Corps，said she often takes her dog to visit high school students around finals time. "This age group benefits really well from just the presence of Waffles or other certified therapy dogs，" she said.
   Therapy dogs must be properly trained and pass a test before they become certified，said Ann Davidson，operations manager at Canine Therapy Corps.
   "Taking breaks is one of several tools students can use to manage stress or anxiety，" said Jacqueline Rhew，a registered clinical professional consultant.Rhew also said，"Trained dogs help students put academic stress into perspective." When students don't properly manage stress，it can turn into troubling anxiety.
   Juniors Jennifer Giraldo and Anastasia Ramirez hugged and laughed as they took turns with their classmates，giving Luna，a Portuguese water dog，commands to sit，lie down and roll over. "I was stressing all third and fourth periods，and then people were talking about the dogs，" said Ramirez，who decided to wait in line with Giraldo to see the dogs herself. "Now I feel better."
