Has anyone used a 'doggybog'? It is basically an extra (flushable) pipe that attaches to your home's outdoor soil pip.

Currently Nando has his own bin which we triple bag and then place in our wheelie bin on collection day. However, recently we have had to re-locate it and as it is no longer shaded we realised it is not water tight and is very quickly filling with rain!!

Thinking of alternatives and came across this:

What a price
We have an oblong main drain cover out the back with a lightweight lid (not one of the cast iron lids) so I just lift that and tip the shovel contents down.

we just flush my girls poops, i read online that my council recomends either double bagging and binning it, burrying it or flushing down the toilet and as we also have an outside toilet that is now the dogs toilet. If only i could teach her to use it herself lol.

I have a compost bin and worms that eat the poo, I'm amazed but it doesn't smell at all with 4 dogs and occasional visitors. I got the compost bin cheap from my local council and bought the worms on ebay :-) The only time I have to bag and bin poos from the garden is when the dogs have been wormed.

I double bag mine and take it with me when I go on a walk and put it in the nearest dog waste bin. I walk the dogs every day so bin the waste every day.
