My 5 month old likes to bark of people or dogs that he isn't allowed to get to close to or if we are just walking by them and he gets no attention from them. It is in no way an aggressive thing. He does, however have a deep scary bark, and frankly, it is embarrassing! Mostly when we are in a place, like, petco, and his bark echos through the store, lol. How do I stop this? Is he ready for a pinch collar or is 5 months still too young? I have been trained by a professional on how to use the pinch collar, but it was with an older (1 year old) dog. What is recommend? And distracting him, doesn't work.
