Outward Hound’s Fire Biterz are a more durable version of your dog’s favorite plush toy. Unlike traditional plush toys, Fire Biterz dog toys are designed with a special K9 Tuff lining, firehose material, and signature squeakers to withstand hours of play. Fire Biterz are a standout addition to your pup’s toy collection. While these plush toys are constructed to last, keep in mind they are not meant as a primary chew toy. Toy contains polyfill.
