Fur is drying after having been wet. Ears get torn off in attacks by dog, or dingo but it has a surprising appearance. At necropsy, the stump of the ear looks like the ear blade was cut off with sharp secateurs. If it was a dingo attack sometime in recent weeks, I expect the muscles of the rump and lower back will still be damaged (extreme bruising and maybe a skin puncture if they got a good grip on).
Maybe torn off getting through a barb wire fence. I wish the ACT and NSW Govs not keep ercting traditional barbed fences when there is no domestic stock to keep out.
