Here’s our d0g Booker; ordinarily very well behaved.
He has this thing for fennel plants. They break apart easily (since they are dry now).Actually some are fresh too but are soft; he just chews them a bit and spits them out too. Like I used to do as a kid!
He is allowed ONE plant per walk in this open space, where we can safely let him run off leash).
Notice he obeyed the leave it command when he chomped into a harder limb (scotch broom),
