Canine Submision 

Forcing somone into submission and to take on the roll of a canine or dog; living in a cage, wearing a collar and usually having their hands immobilizedwith special locking gloves that force the hands into fists so that they look like paws. Prevalent practice in the BDSM community.

Travis was forced into Canine Submission, his master makes him wear a collar and wear a gag in his mouth because dogs can't talk, I hear he even eats out of a dog dish and walks on all fours.
