What is claimed is: 1. A pet vehicle comprising: (a) an undercarriage comprising two forward uprights, a rear wheel fork, and a carriage frame having an open end, a closed end and a mid-frame bar, with the two forward uprights being rigidly attached to the open end of the carriage frame and extending obliquely downward from the open end of the carriage frame, such that the lower ends of the forward uprights attach to the front wheel axle and are slightly offset from either end of front wheel axle, and such that the lower ends of the forward uprights are at an acute angle of approximately 70�� to the horizontal plane; (b) two front wheels, which are rotatably attached to either end of the front wheel axle; (c) one rear wheel, which is rotatably attached to a rear wheel axle, with either end of the rear wheel axle being attached to two fork prongs comprising the rear wheel fork, and with the rear wheel fork being rigidly attached to the closed end of the carriage frame, such that the rear wheel fork extends downward from the closed end of the carriage frame at an obtuse angle not greater than 130��; (d) a pet enclosure comprising a pet platform, a platform rod, a back panel, a panel rod, and two enclosure uprights, with the pet platform being a sheet of flexible material tautly stretched between the mid-frame bar of the carriage frame and the platform rod, which platform rod is secured at either end to the forward uprights, and with the back panel being a sheet of flexible material tautly stretched between the mid-frame bar and the panel rod, which panel rod is secured at either end to the enclosure uprights, which enclosure uprights extend upward from either end of the mid-frame bar; and (e) a steering assembly comprising a handle bar, two steering bars, and one or more handbrakes, such that at either end of the handle bar are two handles, with a hand brake attached to one or both handles, and such that the steering bars extend from the handle bar to the mid-frame bar of the carriage frame, to which they are rotably attached, and thence to the front wheel axle, to which the distal ends of the steering bars are rigidly attached between the respective attachment points of the forward upright and the front wheel on either end of the front wheel axle. 2. The pet vehicle according to claim 1, wherein at the lower ends of the forward uprights, immediately above the point of attachment to the front wheel axle, is a shock-absorber, containing one or more coiled steel springs. 3. The pet vehicle according to claim 2, wherein at the lower end of each fork prong, immediately above the point of attachment to the rear wheel axle, is a shock-absorber containing one or more coiled steel springs. 4. The pet vehicle according to either of claims 2 or 3, wherein the pet enclosure further comprises a pet harness consisting of one or more flexible straps that are attached to a pet and/or a pet collar so as to contain and restrain the pet's movement within the pet enclosure. 5. The pet vehicle according to either of claims 2 or 3, wherein the pet enclosure further comprises one or more support bars that are attached to the two forward uprights and extend around the open end of the carriage frame. 6. The pet vehicle according to claim 5, wherein the support bar(s) extend(s) around both sides of the pet platform to the enclosure uprights. 7. The pet vehicle according to claim 4, wherein the pet enclosure further comprises one or more support bars that are attached to the two forward uprights and extend around the open end of the carriage frame. 8. The pet vehicle according to claim 7, wherein the support bar(s) extend(s) around both sides of the pet platform to the enclosure uprights. 9. The pet vehicle according to either of claims 2 or 3, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements. 10. The pet vehicle according to claim 4, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements. 11. The pet vehicle according to claim 5, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements. 12. The pet vehicle according to claim 6, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements. 13. The pet vehicle according to claim 7, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements. 14. The pet vehicle according to claim 8, wherein the pet enclosure further comprises a retractable cover, made of flexible impervious material, which is attached to the enclosure uprights above the back panel, and which, when opened, extends above the pet platform, thereby protecting the pet from the elements.
