You’re following your dog around the street picking up his business anyway, you might as well add on umbrella holder to your dog butler duties. The Dogbrella from Hammacher Schlemmer is basically an umbrella with the handle on top. It has a 29″ diameter clear canopy and the tip of the umbrella hooks to your pet’s leash to keep it from straying beyond the coverage of the dogbrella. I’ve definitely seen people holding regular umbrellas over their dogs to keep them dry, so this seems like an improvement. Maybe throw on a set of rubber dog boots too and your dog won’t get your entire house wet every time it rains.
