Who thought this was a good idea?

I have two dogs, as regular readers know: Jeb the Wonder Dog, a collie who weighs about 60 pounds, and Sadie the Auxiliary Back-up Dog, who weighs about 10 pounds. Needless to say, they use different leashes, especially since I often walk both at the same time.

Now, in their infinite wisdom, the makers of dog leashes -- and we're talking about retractable leashes here -- make the leashes of different sizes and strengths depending upon the weight of the dog to be walked. Big dogs = heavy-duty leash, small dog = light leash. This makes sense, of course -- at least when you are talking about the actual leash, string, whatever that attaches to the dog. When you're talking about the handset, though, somebody had a failure of imagination. As you can see, the big-dog leash is big, and the little-dog leash is little:

But did they think my hand would get smaller when walking the little dog? Seriously:

All of my fingers fit in the big-dog leash, while I can barely get three fingers in the small one. I understand why the cord is smaller in one than in the other, but my hand is the same size regardless of which dog I am walking. These leashes happen to be from the same manufacturer, but this disconnect applies to all makers. Who the fuck designed these things, and do they own dogs? Or have hands?
