What type of joint sound may indicate a torn meniscus?

A torn meniscus in a canine's knee can result in a clicking sound during movement, which is often referred to as "clicks." This occurs when the torn portion of the meniscus catches between the femur and the tibia as the joint flexes and extends, causing the audible sound. The presence of clicking can be indicative of joint instability or dysfunction associated with such injuries.

Other options such as coughs, flatulence, and stridor do not pertain to joint sounds related to musculoskeletal issues. Coughing is related to the respiratory system, flatulence pertains to gastrointestinal gas, and stridor is a high-pitched wheezing sound associated with airway obstruction. None of these options are relevant to the evaluation or diagnosis of a torn meniscus in veterinary practice. Thus, the sound associated with a torn meniscus is specifically that of clicks, making it the correct answer.
