Bark n’ Roll Canine Care of North Reading last month sponsored a fund-raising event at the Burbank YMCA in neighboring Reading. About 50 puppies and dogs took a dip in the Burbank Y’s therapy pool and raised $1,000 for the Y’s annual fund, which helps to cover the cost of services that the organization providesfor free to families in need, such as swim lessons, child care, and camp programs. The event took place before the Burbank Y’s annual cleaning, when the pool is drained and workers acid-wash both the pool and pool deck. The pool was cleaned and filled again with fresh water prior to the start of the Burbank Y’s fall activities. The Burbank Y, on Arthur B. Lord Drive, serves individuals and families in Reading, Stoneham, North Reading, Wilmington, and Wakefield.
