Abstract: A therapeutic pet pillow and harness is disclosed that assists in maintaining a desired head elevation for a pet to assist pets with a decreased esophageal muscle motility. The therapeutic pet pillow and harness aids in upper digestive system functions my imparting the elevated head positioning during resting periods for the pet. The elevated head positioning helps to decrease the possibility of fluid collection in the esophagus resulting in regurgitation, aspiration and/or failure to thrive. The therapeutic pet pillow and harness includes a cushion having an opening dimensioned to encircle a neck of the pet with an easement between an inner circumferential aspect of the opening. The harness assembly retains the cushion to the pet. A parting line allows the cushion to be opened to facilitate placement of the therapeutic pet pillow and harness about the neck of the pet.
