This holiday season give your canine companion a gift, too, and a healthy one at that. Barkwheats (100 Harris Rd., Stockton Springs, 207-449-1214, www.barkwheats.com) are grain-free, organic, made-in-Maine buckwheat dog biscuits that come in two flavors: seaveg and chamomile, or ginger and parsley. All the ingredients (except the ginger, which helps alleviate canine anxiety) are sourced locally.
