Dog feces brings in flies and all the disease that goes with them.
They are magnets for ticks, fleas, and pollute the heels of shoes more than all other pets put toegether.
Their barking is one of the most annoying sounds on earth, very similar to rap ‘music’.
But I do like German Shepherds, and I’m a sucker for beagles and miniature scotty dogs. And dangit — other dogs too.
