We use to have a dog toilet in the back garden till sean decided to jump on it and went right through the thing, poo knee high in poo and the bioactive stuff that you put in it
but they'e a right pain in the @rse, you've gotta dig a hole to take the bin, make sure there's proper drainage under it, use the bioactive stuff every week to break down the poo hose it out every few weeks OMFG does that no half smell the whole neighbourhood
and if you've got more than 1 dog it's double the poo to get rid of, the bioactive stuff is suppose to break the poo down but i don't think it use to work very well, the poo seemed to stay whole for ever
now i pick up the poo in a doggy poo bag and put it in my bin, dunn o what i'll do with it if the binmen refuse to take it away, suppose i could always toss it over the fence into my neighbours gardens
