MATERIALS AND METHODS Transit time and number of collisions through a maze were recorded for 12 chronically and irreversibly blind dogs. Each dog repeated the maze while fitted with a BlindSight® echolocation device, or Muffin's Halo® physical barrier. They then repeated another maze test after a 30-day device acclimation period at home. RESULTS All dogs had fewer collisions when wearing the halo device versus their baseline with no device. Dogs ≤11.8 kg had fewer collisions when acclimated to the halo versus their baseline with no device or when acclimated to the BlindSight®. For dogs >11.8 kg, maze completion time was faster when acclimated to the BlindSight® versus their baseline with no device or when acclimated to a halo. Owner surveys indicated no noticeable improvement in quality of life or dog navigation at home with either device. CLINICAL SIGNIFICANCE This study demonstrates the utility of commercially available visual aid devices in aiding blind dogs' navigation and may help veterinarians make recommendations to owners of blind dogs regarding the purchase of these devices. © 2020 British Small Animal Veterinary Association.Robert Fine was among the most original social theorists in Britain of the past 30 years, and the aim of this paper is to offer a first systematic assessment of his intellectual contribution. There are sound intellectual reasons to explore Fine's scholarship. He maintained a problematic relation with mainstream sociology and, against the reduction of sociology to questions of method, culture, or class, he argued that sociologists must continue to ask difficult normative questions as part of the social world they ought to explain. And there are also pressing political concerns that justify a reconsideration of his writings. Global politics is currently marked by a populist wave that decries the very ideas and values that were ce
