The Round Tip Bur #2 is used for most canines. Round burs are useful for creating access holes, removing buccal bone, creating a moat around root fragments and smoothing alveolar bone. Latch-Type burs cannot be used in push button handpieces, they are specific for doroit style attachments. Sizes range from 1/4 to #10. The most commonly recommended round burs for veterinary dentistry are the 1/4 and 1/2 for felines and #2 and #4 for canines.
