Rainy days

There once was an overprotective vet,
Whose wiener he would never let get wet.
He made an umbrella,
For his little fella,
But let him drench every passing hydrant.

I've actually seen a neighbour's beagle clad in a doggy raincoat before. But an umbrella? How is a dog supposed to navigate all those nooks and crannies with that big thing hanging over his head? Not to mention the embarrassment that the human will have to endure for being seen with such a tacky contraption. Save it for cartoon dogs, guys.
