A protective boot for an animal including a generally cylindrical leg portion having a top end and a bottom end and a top closure affixed to and circumscribing the top end of the leg portion that is drawn inward against the leg of the animal to protect against the infiltration of extraneous material into and against the self-removal of the protective boot by the animal. The base portion of the protective boot is sealed to the bottom end of the leg portion and is enhanced with a non-slip material to provide substitute traction for the animal. At least one strap is fixedly connected to the leg portion and is operable to reduce the diameter of the leg portion in the vicinity of the strap. The protective boot is sealed at each seam or point of attachment between elements so that the boot is waterproof.
