I believe some dog trainers might have reservations about the use of choke collars because they either lack proficiency in their proper application or because they recognize it as a quick-fix solution to resolve issues. They may prefer alternative, slower methods to prolong the training process and charge clients for additional time. The debate over whether choke collars are painful is subjective. I'm aware of a facility with over 30 years of experience in training aggressive dogs using choke collars alongside other methods. This issue isn't a one-size-fits-all scenario; it's about a group of individuals looking to profit from their services due to the substantial financial potential. One pertinent question to consider is why this individual (Michael Shikashio) blocks people from commenting on his Facebook account. If they genuinely have confidence in their techniques and believe in the truth of their methods, shouldn't they be able to defend their position openly? If they are indeed confident, why haven't they provided a comprehensive video demonstration, from start to finish, showcasing the positive reinforcement technique of training a large aggressive dog with treats?
