5' Foldable Dog Pool $30

This Yaheetech 63" Foldable Pool for Dogs and Kids is only $29.99 at Amazon. Similar ones are $40-$50. This is much better than hard plastic ones because it collapses for easy storage (just fold it up and put it in your deck box!), and unlike the ones with flimsy sides and soft bottoms, these ones are much less likely to tear or leak. It has a 12" depth and an screw-cap drain. Shipping is free with Prime or when you spend $35. Otherwise, it adds $6.99. Editor's note: I'm buying this to give my dog baths outside now that the weather is warm.
