If you want to find out more about the Stagbar the one in this film came from http://www.puredog.co.uk/ and those interesting vegetarian Pigs ears are available at Mutley and Mog who very kindly sent them along for us to test.
Some dogs will chew much more quickly that wussy Tess and Oscar. Our other office dog Ferris, a young GSD, was much more successful at chewing his. He loves his Stagbar but needs to have it rationed. On facebook someone asked if the Stagbar would splinter and I can understand the question. Before I saw these I imagined antlers to be wood-like but really these are more like stone, so I couldn't imagine them splintering from my experience.
