BU’s Mugar Memorial Library was barraged this week by a furry, four-legged squad enlisted to help calm students frazzled by finals stress. A mini golden doodle, a King Charles cavalier spaniel, and, of course, a Boston terrier, were among eight dogs from Dog B.O.N.E.S Therapy who helped soothe sleep-deprived students at the end of the semester. “This is the first time [we’ve had the program] at Mugar, and there’s just such demand. [Students] filled all the reservations within 48 hours of putting signs up,” said Sara Rimer, a BU spokeswoman. “These are certified therapy dogs; they have excellent, calm personalities. And these kids are stressed out. They’re poking their heads into the room and saying ‘Can I get in?’ ” Small groups of students are allotted 15-minute sessions to pet and feed the dogs. Rimer smiled as Annie Oakley, a King Charles cavalier spaniel, bounded up to her. “I feel calmer just being around this dog! She has the most soulful eyes and long beautiful ears. . . . This dog is adorable.” Clearly, puppy love was alive and well in Mugar Library. Dog B.O.N.E.S will return to BU Saturday from 5-7 p.m., with a new group of eight dogs available for belly rubs.
