Review on Dazzber Martingale Collar, Medium, Royal Blue, Neck 14 Inch -21 Inch, No Pull No Escape Dog Collar, Great For Training Walking Running by Stephanie Benoit

Great collar but I am only giving 3 stars because if you have two dogs that play fight this collar can kill yourdog. My puppy was wearing one and the bigger dog got it stuck on her teeth and literally almost choked him to death. We had to get a knife and cut it off of him and hold her still while it was stuck in her mouth. I still like this collar. But I never leave it on them anymore. Only slip it on as needed and then take it right back off. Don't leave dogs unsupervised in this
