Mars Petcare, owners of both the Whistle tracker and the Banfield Pet Hospital chain, is offering a way for Banfield customers to get a free Whistle for their dogs. (Sorry, cats are not eligible.) Banfield members can go here to sign up to receive their free tracker. Mars plans on using the data collected via the Whistle to uncover links between pet activity and their health. The study is called the Pet Insight Project and it will track more than 200,000 dogs over three years.
