Have you ever had any trouble with Opuntias and dogs? I suddenly have three lovely Opuntias [all azurea, I think] but was just told that I'll grow to hate them, since "the wind blows those tiny glochids all over." I worry less about myself than about my three dear old pups. The Opuntias are in pots, above a retaining wall and at least a foot or two back from the wall's edge. Thanks, CactGuy!
I actually have never had irritation issues with the glochids, but on occasion Sophia ends up with spines stick in her head (she’s is more beauty than brains).
