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. ## Claims ### Claim 1 A leash attachment comprising: A housing; a trigger; a cam; a fill hole; a liquid reservoir; a flip open cup; a dispensing mechanism; a grip; and a leash hole. ### Claim 2 (depends on 1) The leash attachment of claim 1, wherein the dispensing mechanism further comprises a body and at least one straw, and wherein the dispensing mechanism is submersible within the liquid reservoir. ### Claim 3 (depends on 2) The leash attachment of claim 2, wherein a first pair of detents keeps the flip open cup in a closed position; and wherein a second pair of detents keeps the cam in place and secures a leash. ### Claim 4 (depends on 3) The leash attachment of claim 3, wherein the flip open cup rests on a top surface when in a closed position; and wherein the flip open cup swings outward to be in an open position, allowing a liquid to be expelled from a nozzle into the flip open cup. ### Claim 5 (depends on 4) The leash attachment of claim 4, wherein the top surface is angled downward. ### Claim 6 (depends on 5) The leash attachment of claim 5, wherein a leash enters and exits through the leash hole; and wherein the cam secures the leash. ### Claim 7 (depends on 6) The leash attachment of claim 6, wherein the trigger is connected to the dispensing mechanism, and wherein the liquid is aspirated when the trigger is deployed through the at least one straw at a first end and to a second end connected to the nozzle. ### Claim 8 (depends on 7) The leash attachment of claim 7, wherein the liquid enters the liquid reservoir through the fill hole. ### Claim 9 (depends on 8) The leash attachment of claim 8, wherein the nozzle expels liquid towards a distal end of the flip open cup when the flip open cup is in the open position. ### Claim 10 (depends on 1) The leash attachment of claim 1, wherein the cam is a rolling structure, with the leash rolling along ridges of the cam. ### Claim 11 (depends on 1) The leash attachment of claim 1, wherein a cap covers the fill hole. ### Claim 12 (depends on 1) The leash attachment of claim 1, further comprising a funnel. ### Claim 13 (depends on 1) The leash attachment of claim 1, further comprising a locating pin. ### Claim 14 A leash attachment comprising: A housing; a trigger; a cam; a fill hole; a liquid reservoir; a flip open cup; a dispensing mechanism; a leash hole; a first pair of detents; and a second pair of detents; wherein the dispensing mechanism further comprises a body and at least one straw and is submersible within the liquid reservoir; the housing further comprises a grip; the first pair of detents keeps the flip open cup in a closed position and the second pair of detents keeps the cam in place when a leash is not attached and releases the cam from the leash attachment when pressed; the cam is a rolling structure with the leash rolling along ridges of the cam; the flip open cup rests on a top surface when in a closed position; the top surface is downwardly angled; the flip open cup swings outward to be in an open position, allowing a liquid to be expelled from a nozzle into the flip open cup; the leash enters and exits through the leash hole; the cam secures the leash; the trigger is connected to the dispensing mechanism; the liquid is aspirated from a first end of the at least one straw to a second end of the at least one straw connected to the nozzle; the liquid exits the nozzle when the trigger is deployed; the liquid enters the housing through the fill hole; the nozzle expels liquid towards a distal end of the flip open cup when the flip open cup is in the open position; a cap covers the fill hole; a locating pin allows for easy assembly of the flip open cup onto the leash attachment and for the flip open cup to be swung into the open position; and wherein a funnel drains unused liquid back through the fill hole into the liquid reservoir from the flip open cup. ### Claim 15 A method of using a leash attachment to provide a liquid to a leashed animal, comprising the steps of: providing the leash attachment comprising: a housing, a trigger, a cam, a fill hole, a liquid reservoir, a flip open cup, a dispensing mechanism, a leash hole, a first pair of detents, and a second pair of detents; placing a leash through the leash hole; securing the leash with the cam and allowing the leash to roll along ridges of the cam; filling the liquid reservoir with a liquid through the fill hole; placing a cap on the fill hole; swinging the flip open cup outward from a top surface that is downwardly angled into an open position; depressing the trigger so that the dispensing mechanism via a nozzle expels the liquid towards a distal end of the flip open cup; and returning the flip open cup to a closed position. ### Claim 16 (depends on 15) The method of claim 15, wherein the dispensing mechanism is submersible within the liquid reservoir. ### Claim 17 (depends on 16) The method of claim 16, wherein unused liquid is directed via a funnel back through the fill hole into the liquid reservoir, with the funnel positioned beneath the fill hole. ### Claim 18 (depends on 17) The method of claim 17, wherein a locating pin allows the flip open cup to swing outward into the open position. ### Claim 19 (depends on 18) The method of claim 18, wherein the first pair of detents keeps the flip open cup in a closed position; and the second pair of detents, when pressed, releases the cam from the leash attachment.
