I usually do mine in the sink, I have a small plastic box, I will it to about 10cm of warmish water (never really hot or cold) I then rinse the piggy all over, just talk to them all the time, nice and slow movements so he gets use to it. Then apply the shampoo, I then wrap them in the towel with the shampoo still on so it really soaks in for about 5 minutes then I replace the water and wash them off. If you are applying conditioner, do the same process as above, if not, really rub them dry and then leave in doors till fully dry and put back out
