Dog pool for the garden
Even the four-legged friends love the water, especially when it's hot. So that the four-legged does not ruin in the garden pond, you can dig in an extra mini-pond only with gravel down there.
The ponds are available in different versions. With steps or completely flat (for small dogs or so many cats), small or larger depending on desire and need.
If that is too expensive, can also take a plastic tub (hardware store) where cement is mixed in it. I have such tubs for my potted plants.
I would paint the pond (eg turquoise or white), so that I too have something for the eye. The imagination knows no limits.
If you then put a few wooden planks or gravel around the edge, the dog does not carry all the dirt from the garden into his pool.
Of course, sometime water change is announced. Then you have to grab the bucket and exhaust it. But what do you do not do for his beloved four-legged friend ...
