Description Source Story: Cruelty-free deer antlers sourced from naturally shed antlers – i.e. the antlers fall naturally from the deer, without any intervention. These deer antlers come from Tasmanian and South Australian deer and are cut and weighed at our little farm in Bannockburn. Feeding Guide Antlers are fantastic, long lasting chews. They are great for dental health & are odourless (yippee!) for indoor chewing. When the appropriate size is selected (size up if in doubt) then the antlers will not splinter and last 2-3 months on average. Dogs gnaw on them slowly to wear them down. These are best for toy and small breed dogs.
