Dog owners have most likely heard of the slogan "bag it and bin it", when it comes to dealing with dog poo. But according to the Forestry Commission, although lots of owners are now getting the "bag it" message, more and more of them are failing to "bin it".

Many forests across the region are littered with bags of dog poo. From being left on the ground, hung in the bushes, and arranged carefully on tree stumps.

And the Commission says the problem is only getting worse...

The Commission does provide poo bins in the car parks. But for more remote areas, such as Stockhill Wood in the Mendips, a new system is being introduced: "stick and flick".

In other words, get a stick and flick the dog poo into the undergrowth.

Despite dog poo being biodegradable, it can carry roundworm eggs.

If you get it on your shoes, when you take your shoes off or your boots off after a walk, if you don't wash your hands, you can basically eat the eggs from the worm and you can get a nasty infection called toxicariasis.

So what would a scientist do with dog poo?

The Forestry Commission is hoping that soon less poo bags will be seen dangling in the trees.
