Shapoopie
Heard about this again on NPR and I had to check it out. Telescoping arm to reach out and catch it in a disposable container before it hits the ground. The reviews are the most interesting, those who had actually tried it generally thought it worked. Easy to carry, sturdy, ergonomic. The main concerns among commenters related to function were scaring the dog and making it move, therefor missing some poo; not being able to get it out and extend the arm fast enough; and related to that having no auxiliary scoop function to pick up something that was missed.
However the number one objection had nothing to do with the basic design. People were most concerned that they would look like yuppie fussy jerks using this product. By and large the comments were that people would be embarrassed to be seen using this. Also one mention of the lack of biodegradability if the disposable container so also green concerns. (Are my poop bags biodegradable?)
One person who did like it suggested interesting modifications; scoop, light, adjustable angle to the handle. At any rate, it seems that most people thought it was over-engineering a solution to a problem. It does not seem to be available anymore. The last mentions of it are from 2010.
Still, more people have dogs than ever and with cities seeing a revitalization, there are lots of dogs in the city. Is there a better solution...
