Our first berner, Nova is almost 10 months and we haven't trimmed her long, whispy hairs that seem to grow right behind, below and around her ears. We think they're great but are a little more hassle now that they are collecting more debris, and aren't her favorite areas to be brushed. They're starting to get tangled more often so is it time to clean them up somewhat? Just wondering what those of you who have owned berners do and if you have any tips for tools or methods to do the job. Thanks!
