It's important to keep in mind that excessive barking can be a behavior issue that needs to be addressed through training and socialization. Proper training and socialization can help to minimize excessive barking in PBGVs. It's also important to provide them with plenty of exercise and mental stimulation to help channel their energy in a positive way. With consistent training and attention, PBGVs can make wonderful companions that are both alert and well-behaved.
