Many of us train our dogs to pee and poop on newspapers or wee-pads.
Now, my friend has constructed his own home-made dog toilet and he welcomes new ideas to improve it. The toilet is environment-friendly, and he does not waste newspapers nor waste money buying wee pads. Most importantly, his dogs are kept clean, and their feet kept dry.
View the video of the dog toilet here.

But remember to read the explanation below his video.
Oh, he uses toilet tissue to pick up the dog poop. That is not so environment-friendly. Perhaps he should just use his bare hands to do it, and wash his hands after that.
