Most dog owners are completely unaware of the risks and frequency of collar strangulation accidents until it’s too late. Prevent needless strangulation injuries and deaths with the KeepSafe® Breakaway Collar. The KeepSafe® Breakaway Collar is the only collar that has a patented safety buckle that is designed to protect dogs from strangulation or injury. The most frequently reported accidents occur while two dogs are at play, on fences/decks, crates/kennels, heating/cooling vents, and branches or shrubs.
