When your puff needs some cleaning get a rag and dampen it, not so much so that it´s soaked, just enough so that it is damp. Then use the rag to clean of the dirty fur. If you don´t want to use a rag, or can not for some reason, you can fill a spray bottle with water and spray your pygmy 1-2 times then brush the damp area. If you want your pygmy puff to smell just as good as it looks, mix some conditioner with the water in the spray bottle. You can´t give your puff a bath because they have short little legs and can´t swim. So if you looked away for even just ten seconds, they could drown.
