Our Squeaker Square products are our only products available with squeakers. These toys are made from the large and very durable rubber lined inner layers of the attack hose from many fire departments. Each square measures approximately 5.0"-5.5" by 5.0"-5.5" Like any chew toy dog parents should supervise their dog while playing with this toy and remove the toy if it becomes ripped and torn apart. Any purchase of a product made from hose from a specified Fire Department will help support that Fire Department. Go Go Dog Toys will donate $1 from each toy sold to the fire department who the hose came from.
