As a dog owner I’d have cause to be smug about this, but Kira (like many dogs) really, really, really likes the taste of cat shit and goes out of her way to dig it up from under bushes and playground bark-chip.
Unless canine digestive tracts are really acidic or something, I imagine she’d at least pass the live parasites through. I do my bit for neighborhood hygiene by bagging her own crap, so the woims wouldn’t get any farther than that.
