A protective pet dish apparatus that provides protection from birds and insects of food or water in a pet dish by a protective pet dish cover that is supported by a rod extending from the pet dish to the cover. The protective pet dish cover swivels away from the pet dish on the rod when a pet pushes its head against it and swivels back to cover the pet dish after the pet removes its head from the pet dish. The protective pet dish cover uses gravity or a combination of gravity and magnetic force along with the support and swiveling of the support rod to cover the food after a pet removes its head from the pet dish.

1. A protective pet dish apparatus comprising: a pet dish having a base, a top and a bowl portion, the top having a size and shape;a substantially vertical shaft within the bowl portion extending toward the top, the substantially vertical shaft comprising a cylindrical opening surrounded by at least one shaft wall;a support rod comprising a cylindrical shape at a bottom end sized to fit within and pivotally rotate within the cylindrical opening of the substantially vertical shaft, the support rod further comprising an angled portion, and a top end comprising a support plate, the top end of the support rod positioned along a pivoting axis of the cylindrically shaped bottom end; anda dish cover comprising a top and a bottom, the bottom sized to approximate the size and shape of the top of the pet dish, the top comprising a cover plate positioned along a center axis of the dish cover;wherein the dish cover is biased to a closed position, centered over the pet dish. 2. The protective pet dish apparatus of claim 1, wherein the support rod plate comprises ferromagnetic materials and the cover plate comprises ferromagnetic materials and at least one of the support rod plate and the cover plate is magnetized. 3. The protective dish apparatus of claim 1, wherein the dish cover is biased to its closed position by magnetic attraction between the support rod plate and the cover plate. 4. The protective dish apparatus of claim 1, wherein the substantially vertical shaft comprises an extension that extends through the base of the pet dish. 5. The protective dish apparatus of claim 4, further comprising a gasket that surrounds the extension between the vertical shaft and the base of the pet dish. 6. The protective pet dish apparatus of claim 1, wherein the substantially vertical shaft is positioned in approximately in a center of the bowl portion. 7. The protective pet dish apparatus of claim 1, wherein the dish cover comprises a handle extending from the top of the cover. 8. The protective pet dish apparatus of claim 1, wherein at least one of the support rod plate and the cover plate comprises a substantially flat surface. 9. The protective pet dish apparatus of claim 1, wherein at least one of the support rod plate and the cover plate comprises a semi-circular top surface. 10. The protective pet dish apparatus of claim 1, further comprising a bearing wheel between the support rod and an internal wall of the pet dish cover. 11. The protective pet dish apparatus of claim 10, wherein the bearing wheel is mounted to the support rod. 12. A protective pet dish apparatus comprising: a pet dish having a base, a top and a bowl portion, the top having a size and shape;a substantially vertical shaft extending upward at the center of the bowl portion;a cone-shaped pet dish cover comprising a narrow top and a wide bottom, the narrow top comprising a cover plate having a ferromagnetic material and a flat, planar surface on an inside surface of the pet dish cover; anda support rod comprising a bottom end configured to pivotally rotate on the shaft, the support rod extending from the shaft to the narrow top of the pet dish cover and of a length to support the pet dish cover above the top of the pet dish, the support rod comprising a support rod plate at a top end having a ferromagnetic material and a flat, planar surface which contacts the flat, planar surface on the inside surface of the pet dish cover when the support rod supports the pet dish cover;wherein the support rod supports the pet dish cover such that the pet dish cover is centered over the pet dish and when force is applied to the wide bottom of the pet dish cover to shift the pet dish cover off-center in relation to the pet dish, magnetic attraction between the cover plate and the support rod plate biases the pet dish cover back to its closed position centered over the pet dish. 13. The protective pet dish apparatus of claim 12, wherein at least one of the support rod plate and the cover plate is magnetized. 14. The protective dish apparatus of claim 12, wherein the substantially vertical shaft comprises an extension that extends through the base of the pet dish. 15. The protective dish apparatus of claim 14, further comprising a gasket that surrounds the extension between the vertical shaft and the base of the pet dish. 16. The protective pet dish apparatus of claim 12, wherein the dish cover comprises a handle extending from the top of the pet dish cover. 17. The protective pet dish apparatus of claim 12, further comprising a bearing wheel between the support rod and an internal wall of the pet dish cover. 18. The protective pet dish apparatus of claim 17, wherein the bearing wheel is mounted to the support rod. 19. The protective pet dish apparatus of claim 12, wherein the support rod comprises at least two angled bends in the support rod, one positioned above the shaft to angle the support rod from the center of the bowl portion toward its edge, and one positioned in the support rod near the edge of the bowl portion to angle the support rod from near the edge toward a center axis of the bowl above the shaft. 20. The protective pet dish apparatus of claim 19, further comprising at least a third angled bend in the support rod, the third angled bend positioned near the top end and angled to align the support rod with a pivotal axis of rotation for the support rod in relation to the shaft.
