De-bleated


Devocalization (also known as ventriculocordectomy or vocal cordectomy and when performed on dogs is commonly known as debarking or bark softening) is a surgical procedure applied to dogs and cats, where tissue is removed from the animal’s vocal cords to permanently reduce the volume of their vocalizations.

Devocalization is usually performed at the request of an animal owner (where the procedure is legally permitted). The procedure may be forcefully requested as a result of a court order. Owners or breeders generally request the procedure because of excessive animal vocalizations, complaining neighbors, or as an alternative to euthanasia due to a court order.

Contraindications include negative reaction to anesthesia, infection, bleeding, and pain. There is also the possibility of the removed tissue growing back, or of scar tissue blocking the throat, both requiring further surgeries, though with the incisional technique, the risk of fibrosis is virtually eliminated.

The devocalization procedure does not take away a dog's ability to bark. Dogs will normally bark just as much as before the procedure. After the procedure the sound will be softer, typically about half as loud as before or less, and it is not as sharp or piercing. So while the procedure does not stop barking or silence the animal completely, it is effective at reducing the sound level and sharpness of the dog's bark.

Most devocalized dogs have a subdued "husky" bark, audible up to 20 metres.

The National Council on Pet Population Study and Policy (NCPPSP) is a council of ten prominent American animal organizations which studies and addresses statistics on companion animals.

The NCPPSP's Shelter Statistics Survey collected data from over 5,000 shelters, The study concluded that neither excessive vocalization nor general "behavior problems" were among the top ten reasons companion animals are relinquished at shelters.

In a study of 12 shelters reporting behaviors of animals relinquished to shelters as reported by prior caretakers, a majority of relinquished cats and dogs were reported to have "rarely or never" been too noisy. Conversely, approximately 43% of dogs were reported as too noisy "sometimes", "mostly", or "always", while cats were similarly described as too noisy for approximately 26% of respondents.

The procedure may be performed via the animal's mouth, with a portion of the vocal folds removed using a biopsy punch, cautery tool, scissor, or laser. The procedure may also be performed via an incision in the throat and through the larynx, which is a more invasive technique. All devocalization procedures require general anesthesia.
