    Usually staining is caused by some type of metal or mineral, does any of you know if its toxic to animals? Why I ask is I just had a load of oak dropped off earlier today and my pup has been licking the black staining on the cut end of a log to the point his tongue is stained.

    Believe some of that is starch oxidation.

    He will Be will be fine. Dogs are designed to eat sticks. I think mine can live off of them.

    Yeah Dogs are VERY resilient, no problem.
    My dog licks stinging nettle off my legs and eats coyote ****.....seriously.

    I have a better tolerance for tequila but that's about it.

    He was not happy when I shoveled this pile of junk into the stove.

    Other day him and my lab ate most of a pail of sawdust. We use it in the shop to absorb oil, diesel, etc.

    I happened to walk by and they were chomping down like it was a pail of bacon.

    It doesn’t seem like saw dust would digest well and might cause some issues with an intestinal blockage. Sticks are one thing but a pail of saw dust probably isn’t good.

    Choppy choppy,

    I bet your dogs are wood thieves like mine. Her favorite thing is when I go out to split. She will literally wait for me to turn my back and she’ll try and sneak one of the splits away to chew on.

    Here is my best friend
