Use this general infographic to find the right size chew toy for your dog! Generally, there are three basic chewing styles when it comes to dogs and their toys. Soft Chewers: These dogs are easy on toys and prefer plush to fabric toys. They rarely destroy their toys. Moderate Chewers: These dogs love to play with all kinds of toys. They can be destructive with plush toys but generally not with rubber toys. Strong Chewers: These dogs are usually strong, determined chewers who tend to be destructive with their toys. Choose a durable, interactive toy along with hard rubber toys. Regardless of chewing temperament always supervise play until you are sure the dog will not destroy the toy. Always replace any toy with rips, tears or cuts in it.
