Bought this for my nephews aged three and six. I had seen it on a BBC chat show and it seemed like fun and it was. It was for the six year olds birthday and we had hours of fun feeding the dog and scooping up the poop. It was a great present and pretty much made the day.
Visiting them two weeks later, they immediately wanted to play 'Doggie Doo' and it did not work anymore, due to a serious design fault.
The 'doo' is a jelly like compound similar to a product called 'Gak' and is indeed fun to touch. Very tactile, it has that revolting/fascinating combination. The only problem is, after only a little bit of handling, it loses elastcity, contaminated by moisture of the hands. The toy works by air pressure and if the doo allows air past it, it ceases to work. This led to the doo becoming jammed in the toy halfway and having to spend five minutes unjamming it....only to have the same thing happen on the next bout. It was frustrating for the boys and for me as we had had great fun with it.
There was no address to order more of the compound and effectively, they only played with the toy a handful of times. To keep the compound functioning, you effectively had to ask them not to play with it, keep it meticulously clean and touch it as little as possible! Yes.........!
Overall, Doggie Doo is a superb idea and fun game, but with young kids, only expect to play with it a few times.
