Only allow chewing under direct supervision. Not suitable for dogs under 6 months. Regularly inspect for signs of breaking, loose pieces, or wear and replace when necessary for your dog's safety. While it’s generally safe if small fibers of the wood pulp are inadvertently ingested, this product is NOT meant for internal consumption. Watch your dog closely and discourage them from swallowing any pieces of this chew. The dog’s saliva naturally softens the wood. If the ends get brittle from chewing, you can wet the chew between sessions to make it a little more gentle for your pal.
