Sure! First of all, our dog uses a tray, rather like a cat. We fill it with sawdust or coir (and sometimes planer shavings), and it soaks up the urine. We scoop off solids and put them into a barrel that I drilled a load of holes into for drainage/aeration. I have 3 sizes of container: a 20-litre bucket for collection, a 110-litre barrel and a 200-litre barrel, which I cycle the materials through as each gets filled. That makes turning easy, and gives me over a year to age everything. The compost then goes to fertilize fruit trees, so no direct contact with food sources.
