Abstract: A dog training bumper cover having a porous manufactured sleeve is disclosed and described. The porous manufactured sleeve can have an inner surface and an outer surface. A layer of feathers can be attached to the outer surface via an attachment member. The feathers can be attached in either a random or imbricate pattern. Further, the sleeve is configured to at least partially cover a corresponding dog training bumper. These bumper covers can allow for substantially improved marking abilities while also providing a reusable training device suitable for use in water environments which can dry quickly sufficient to substantially reduce growth of mildew, fungus or attraction of insects, as well as substantially reduce rot and degradation of the bumper cover.
