ChewFactor 3 (CF3)

CF3 Chewers are avid, strong, chewers that often destroy whatever they are chewing on. Our own son is a CF3 chewer so we understand the challenges of this type of chewer. This is the chewer who if they do not have a chew during school, will bite on everything- pencils, desks, hands, fingernails- just about anything. They will also come back home with their sleeves and collar of their shirts dripping wet from chewing on them.If your child's pencil (after a few days at school) looks something like this below-

there's a good chance your chewer is a CF3 Strong chewer and needs an appropriate CF3 chew. Chubuddy is the only chew maker that offers a 90 day, No-Chew-Thru Warranty on it's CF3 Strong chews. If your chewer chews through it in 90 days just email us with a picture and we'll send you a new one. Hardness/Softness Strong chewers can select from soft (70A durometer) chews like the Zilla chews to hard (90A durometer) in our Strong Chew products.


NOTE: Every child is different and need varying levels of adult supervision when using a chewing device. We recommend adult supervision at all times. This is intended only as a guide to the proper selection of a chew for your child. When in doubt please consult a professional Occupational or Speech Therapist familiar with your child.


ChewFactor 1 Light chewers (CF1 chewers) don't usually damage the things they chew on.  They still need a chew to calm and self-regulate.  CF1 chewers are fortunate to have the widest chew selection of all chewers.  

ChewFactor 2 Medium chewers are moderate chewers who occasionally may bite through a light chew.  CF2 chewers need a chew to help them calm and self-regulate.  CF2 chewers typically don't bite through medium chews which are typically thicker, fuller bellied chews with no extraneous appendages.

ChewFactor 3 Strong chewers are avid, aggressive chewers that often bite through most chews within a short time.  They have a very strong need to chew and seek all sorts of things to chew on.  Offering Strong chewers a better alternative to poorer chewing choices is very important.



Strong Tubes come in Big 9/16" diameter and Regular 1/2″ diameter widths. The Big Strong Tube is ChuBuddy's strongest product. You should start with the Regular or Big sizes if you have an aggressive chewer.  All Strong Tubes are hard and smooth. They are rated ChewFactor 3, which means they are among our most durable chews. 

Strong Tubes are hollow and are available on a clip-on or neck lanyard. They are made in the USA. 

Children should not run with a Strong Tube in their mouth.  Wash tubes with warm, soapy water or place in the dishwasher on the top rack.
