Chuckit! Air is a line of Pet toys designed to helps dogs breathe easier when playing fetch. 

Something that could become an issue while playing fetch with your pet is hyperventilation. When this happens to dogs, having a solid toy in their mouth can block air from freely moving and can compound the problem.  The Chuckit! Air toys address this issue by allowing air to move through the toy and not blocking the air way of the dog. The openings on the toys are designed so that air can move through them with ease and yet still be durable.
