Review on Dazzber Dog Collar Martingale: Heavy-Duty Nylon No Pull Pet Collar for Medium and Large Dogs by Sarah Mohamed

Great collar but I'm only giving 3 stars because if you have two dogs fighting this collar can kill your dog. My pup wore one and the big dog got stuck in his teeth and literally choked him to death. We had to take a knife, cut it off and hold her still while the knife got stuck in her mouth. I still love that collar. But I will never let them do it again. Put it on only when necessary and then take it off immediately. Don't leave dogs unattended
