Coffee wood Chew is a way to keep your dogâ??s teeth clean and give them a satisfying chew at the same time. When your dog chews on coffee wood, the wood releases small fibres that have a similar effect to dental floss on your dogâ??s teeth. Chewing on coffee wood is perfectly safe and the fibres that come from the wood can be swallowed and digested without any harm to your dog. The dog chew stick mechanically cleans the teeth and also strengthens the jaw muscles.
