hahahahahahaaaaa Sorry did not mean to laugh out loud.
I have a Chocolate Lab that is going to be 9yr this fall and she is finally matured. Yes, Labs are a fun breed to have in your home. Be thankful that your furkid is only eating sticks. Sasha eats twigs also I try to take them away but she usually gets some in her belly. She has not had any medical trouble with eating the wood...yet.
After we got our Chocolate I learned that the Yellow Labs mature at the earliest then the black then the chocolate.
