Canine devocalization should only be performed by qualified, licensed veterinarians as a final alternative to euthanasia after behavioral modification to correct excessive vocalization has failed and after discussion of potential complications from the procedure with the owner. When dogs are housed in groups (e.g. laboratories, breeding facilities, kennels) devocalization should not be used as an alternative to appropriate animal management and facility design.
