Abstract: An apparatus for the prevention of a dog from inhaling a weed seed includes a collar assembly that secures the apparatus around the neck of a dog and is adjustable in length. A snout assembly includes a pair of side plates that are disposed in a parallel spaced-apart orientation on either side of a snout of a dog. A mesh is disposed intermediate at least a portion of the side plates so that the mesh is disposed over a nose portion of the snout of the dog when the apparatus is worn by the dog. The mesh prevents the dog from inhaling certain weed seeds, for example, a foxtail seed through its nostrils and into its nose.
