Yes – with a warning. Most bark collars respond to a bark with a negative stimulus: citronella spray, ultrasonic sound, or a brief shock. The problem, and the warning, is for homes with multiple dogs or even dogs nearby. For this reason, many bark collars come with adjustable levels of sensitivity, making it harder to set off or easier, depending on your specific situation. You don’t want your dog getting negative reinforcement when another dog is misbehaving; of course because it’s cruel but also because it will confuse him and make the collar worthless. So use these collars carefully and never when he’s in the company of other untrained dogs.
The term personality has been applied to human research, whereas the term temperament has been mostly used for animal research.[18] However, both terms have been used interchangeably in the literature, or purely to distinguish humans from animals and avoid anthropomorphism.[19] Personality can be defined as “a set of behaviors that are consistent over context and time”.[20] Studies of dogs' personalities have tried to identify the presence of broad personality traits that are stable and consistent over time.[19][20][21][22] more on this
