A system for providing fluid for an animal includes: a generally oval trough to contain fluid, wherein the vertical inner sides of the trough slope inwardly from the upper rim of the trough to the bottom of the trough at an angle that varies around the circumference of the oval, there is an opening in the bottom of the trough in fluid communication with a dip tube that extends into a partially flexible fluid reservoir, and a means of attachment on the underside of the trough by which the fluid reservoir is sealably attached so that when pressure is applied to the reservoir, fluid will flow upward through the dip tube and fill the trough, and when the pressure is released, any remaining fluid will return to the reservoir.

A pressure regulator for controlling flow of a fluid therethrough is provided. An upper housing member and a primary diaphragm define an upper chamber and a lower housing member and the primary diaphragm define a lower chamber. The pressure regulator further includes: a valve assembly provided within the upper chamber for controlling the flow of the fluid from an inlet body into the upper chamber; a secondary diaphragm provided within the lower chamber and defining a secondary diaphragm driving chamber; and a passageway connecting the inlet body and the secondary diaphragm driving chamber. During operation, the secondary diaphragm driving chamber is filled with the fluid at the inlet pressure, thereby subjecting the secondary diaphragm to the inlet pressure and generating the force for actuating the valve's disengagement from the inlet body. The pressure regulator functions to maintain the outlet pressure at a value that is a predetermined fraction of the inlet pressure.

A water dispenser actuating device for activating flow of water from a dispenser to a bowl includes an actuator that is configured to be selectively coupled to a water dispenser so that the actuator is operationally coupled to a flow valve of the water dispenser. The actuator is configured to be selectively actuated by at least one of a user and an animal, via application of a downward force to the actuator, to actuate the flow valve so that water flows to a bowl of the water dispenser.

A base for pet feeder and a pet feeder for eating or drinking of pets are provided. The base includes a main body portion and a plurality of adjusting mechanisms. The main body portion includes a first side and a second side, the second side is disposed opposite to the first side, and the first side is configured to contain food or water. The plurality of the adjusting mechanisms are disposed at the second side of the main body portion at intervals, each of the plurality of the adjusting mechanisms is capable of providing at least three heights. Each of the plurality of the adjusting mechanisms includes a first supporting plate and a second supporting plate. The first supporting plate includes a first part and a second part, the first part is rotatably connected to the second side.

A leash attachment and method for using the leash attachment are provided. The leash attachment has a built-in flip open cup that allows an animal to drink from the flip open cup once liquid is expelled to the distal end of the cup via a nozzle. Unused liquid from the flip open cup drains back via a funnel into the leash attachment by way of a fill hole. The leash attachment attaches to a leash via a rolling cam with ridges on the cam's outer surface.

An animal water dispenser apparatus has a container with an interior defined by wall and a bottom, a tubular member connected to an inlet of the container, and a water hose connected to the inlet. The tubular member has a plurality of openings that open to the interior of the container. The water hose is adapted to pass fresh water into the tubular member, outwardly of the plurality of openings of the tubular member, and into the interior of the container. The outlet is adapted to allow water from the interior of the container to be released outwardly of the container. A fresh water source can be connected to the water hose so as to pass fresh water under pressure through the water hose.

A feed and water distribution device with a housing and a drip edge that hangs over protecting one or more feed ports or openings in the housing of the device. Each opening can be fitted with a plug that may also feature a shelf, wall and/or a drinking or watering valve. The housing of the device is shaped such that a portion of it covers the opening(s) in the housing through which feed and water can be obtained by animals. The housing can feature a drip edge. Optional plugs fit into the openings and can feature watering valves that can be manipulated by animals to dispense water. The interior cavity of the housing can be fitted with a funnel to direct the feed toward the center of the interior cavity. The floor of the housing can be cone shaped to help direct feed passing through the funnel towards each opening.
