A collar for pets includes an adjustment belt and a neck belt wherein the adjustment belt has a plurality of engagement holes equidistantly distributed at the surface of one side thereon, and the neck belt is provided with an engaging hoop attached at one side thereto. At the other side of the adjustment belt and the neck belt are respectively disposed a first and a second coupling hoops with a first and a second movable coupling belts attached at the other side of the coupling hoops thereof. The first/second movable coupling belts are respectively provided with a D-shaped first/second leash hoops at the outer side of the other end thereof, and a first/second passages disposed at the middle section thereon for holding a male and female buckle pieces with elastic buckling legs and buckling holes disposed thereon respectively. Thus, the collar thereof is adjustably looped around the neck of a pet with the D-shaped first/second leash hoops guarded at the front outer side of the male and female buckle pieces before the leash hoops thereof hitched to a hook of a leash to form two layers of retaining points for double buckling safety. In case the male and female buckle pieces are mutually disengaged due to the joggling or nuzzling of the pet, the hook of the leash can still hitch precisely onto the D-shaped leash hoops of the collar, effectively preventing the pet from running off instantly from the collar and getting lost.

The present invention relates to an animal safety collar and methods of operation. One embodiment of the present invention relates to an animal safety collar including a strip of flexible material, an extendable material, a first coupling device, and a second coupling device. The extendable material is coupled to either end of the strip of flexible material so as to form a loop. The loop's circumference may be temporarily increased by expanding the extendable material, causing the ends of the flexible material to move away from one another. This capability allows the collar to expand so the animal can slide out of the collar when it is inadvertently coupled to a fixed object in an unsupervised scenario. The first and second coupling devices are fixably coupled to the ends of the strip of flexible material, respectively. Therefore, when the extendable material is expanded, the first and second coupling device move away from one another. The expanding capability may be disabled by rigidly coupling a device simultaneously to the first and second couplers, thereby preventing them from moving away from one another. Therefore, the expandable safety feature may be disabled when an animal is in a supervised scenario such as a walk.

A service dog harness has a base member and a strap system for attaching the base member to a dog. A rigid platform is provided on a top side of the base member, and a soft cushion material extends under and beyond the sides of the rigid platform to impart a soft cushion feel over the underside of the base member. A collar strap assembly is attached to the front end of the base member and is adjustable to fit about a dog's lower neck and chest in front of the forelegs. A trunk strap assembly is connected between the left and right sides of the base member and is adjustable to fit about a dog's trunk behind the forelegs. A ventral strap is connected between the collar and trunk strap assemblies. Padded sleeves cover the collar and trunk strap assemblies to minimize discomfort to a dog wearing the harness.

An animal restraining harness includes first and second straps connected at opposed ends to connectors. A center chest strap extends between the first and second straps. A flexible restraining strap is looped between the connectors and is attachable to a leash. The restraining strap enables the first and second connectors to be pulled together reducing the diameter of the second strap as a result of a pulling movement of an animal wearing the harness which applies pressure on the rib cage of the animal.
