If there is anything worse than finding dog poop under your shoe, it is most certainly seeing dog poop rolling and flinging off of a stroller wheel and onto your pant leg.
Your dog is obviously extremely ill. How else do you explain the identically-shaped turds at regular intervals along the sidewalk of Chorro Street? This was not the work of a team of dogs. This was one dog. Yours.
Might I suggest that you investigate the BRAT Diet for your poor pooch? (It has done wonders for my oft loosey-goosey Seabass.) Or perhaps a well-stocked, handy cache of plastic bags would do the trick?
Either way, if I find your dog’s excrement on the tire of my stroller again, I will hunt you down and force-feed your dog Immodium AD with my own two hands.
