With all the collars I have tried and used over my years of owning and working with large breed dogs, this is by far the best collar for training, everyday walking and safety.. Safety being for me a big thing.. I don’t personally leave a collar on unattended dogs anymore but then that means no tags, but my fear of being caught up and choking or becoming traps scares me more, I have known too many bad situations to risk it anymore but this collar, this collar allows for breakaway if a situation occurs but only when a lead is not attached, when the lead is attached this collate feels safer than any collar, secure and reliable, loose for comfortable walking and off lead plus safety, then when required firm and unable to slip off the head so it’s perfect.. No more adjusting collars to suit comfort or avoiding the collar coming off over the head on dogs who flip and pull and twist out, no more tight collar where you feel if you don’t have it this way they may escape.. 10/10 with the button connection, not the other types, the button connection is the whole reason this collar takes the lead in my opinion..
