Dog Pond - Place a plastic kiddie pool in the ground. It'd be easy to clean and looks nicer than having it above ground. Big dogs can't chew it up or drag it around. This is obviously more fancy than a plastic kiddie pool underground, good idea thou
They say "doghouse", but I see "chicken coop". Lol "What a great dog house. Can go inside if they want, or out on the porch if they want and still contained without having to be on a chain. Plus no mud when it rains.
Hidden dog crate - no DIY instructions as this is for sale but can totally DIY this for less! If I ever got another dog I am so doing this, no crate in house, no dog bed spread over the floor and I'd have space to display :D
