DETAILED DESCRIPTION
Throughout this description, embodiments and variations are described for the purpose of illustrating uses and implementations of the invention. The illustrative description should be understood as presenting examples of the invention, rather than as limiting the scope of the invention.
It may be difficult for a quadruped to exit a body of water where the depth of water at the desired exit area is greater than the length of the quadruped and the exit area provides limited traction features. For example, a dog attempting to exit a pool with no shallow area or climb onto a boat or other floating area such as a deck in water having a certain depth may have a difficult if not possible task. The dog may require assistance, which may be difficult depending on the size and weight of the dog and the specific exit area environment. The present invention provides embodiment of an inflatable, floatable exit ramp system (IFWER) that enables a quadruped to more easily and safely exit a body of water to a desired exit area (such as a deck, boat gunnel, pool periphery, or other exit area).
