Kaylee Wiroll of Dracut, a 7-year-old student at St. Michael School in Lowell, recently raised more than $1,400 to donate a bullet and stab protective vest for K9 Joka of the Suffolk County Sheriff's Department through Vested Interest in K9s. She is featured in the 2013 Vested Interest in K9s Calendar for the month of September with Cpl. Tim Frates and K9 Joka. She will appear with the K9 team from the department on Saturday, Oct. 13, from 10 a.m. to 2 p.m. at Skipton's Pet Center 274 Southampton St. Boston, autographing calendars, which are available for $15. Proceeds will go toward vesting Jax, the department's newest K9 in training. PHOTO BY BETTY LINDBLOM, 5 DOGS PHOTOGRAPHY
