A device for controlling the behavior of an animal, which animal has a neck, eyes, and a head, is provided. The device includes a collapsible hood having a length extending between a collar end and a muzzle end. The collapsible hood is configurable in a collapsed state wherein the collar end and the muzzle end are in close proximity to the collar. The collapsible hood is lengthwise extendable into a deployed state, wherein the collar end and muzzle end are separated from one another and the hood covers at least a portion of the animals head including its eyes. In the collapsed state the device when mounted on the animal does not diminish the animals ability to interact with, or sense, its environmental surroundings. In the deployed state the collapsible hood is operable to substantially diminish the animals ability to sense environmental surroundings outside of the hood using one or more of vision, smell, and hearing.
