Dogs that have allergy or yeast issues typically do worse on regular bone broth that has been cooked for an extended amount of time with vinegar.
When you want your yeasty beasty itchy dog to have bone broth, it has to be homemade and cooked no longer than two hours, without vinegar.
This is due to the high histamine load that occurs in the broth when it’s cooked the traditional way.
