Outward Hound’s Fire Biterz are a mess-free, durable version of your dog’s favorite plush toy! Unlike traditional plush toys, Fire Biterz are designed with a special K9 Tuff lining, firehose material, and signature Invincible squeakers to withstand hours of interactive play. Fire Biterz are a fun addition to your pup’s toy collection. While these plush toys are constructed to last, keep in mind they are not meant for aggressive chewers.
