We have one ol' farm dog on our route that we try to quietly sneak by. His house is back aways from the road, so often we get by without being spotted. If he does give chase it's a good incentive to get us up the next hill.
The funniest are yards with dachshunds. We pass a couple of places were there is a whole little yappy pack of them. Fortunately they're fenced, so they don't get in the road. I think my next dog will be a dachshund.
