ABSTRACT:
A gas mask assembly for snouted animals is disclosed having a nose cap member for covering the nostrils and anterior portion of the animal's snout and having an opening therein for the attachment of a breathing tube. An abutment in the nose cap member prevents the animal's nostrils from becoming occluded by said nose cap member. A flexible sleeve member, formed from substantially gas impermeable material, is secured to the nose cap, and an immobilizing cinch is secured to the marginal portion of the sleeve member to afford sealing engagement for the sleeve member against the animal's snout and to restrain the animal's movements.
