Just make sure the Hibiscrub is really really diluted as it is extremely drying.
I would probably just keep slathering on the Aloe Vera gel !
Thanks Penel. Well I got in yesterday to find Bella had turned into a chocolate roan - the dogwalker did ring me in the afternoon saying "I just want to apologise for the state you'll find Bella in - she ran off for a mud bath before I could stop her and she's a bit, erm, brown"

She was absolutely covered so went straight in the shower and even after a shampoo and several rinsings, I wrung out her ears and the water was still dark brown

.
Anyway I have been slathering on the Aloe Vera this morning and she seems to quite like it being put on so we'll see how she goes. Little does she know today is the last day before she starts getting tormented by Zorro. She's on a full day out with the dogwalker to deliberately get her exhuasted (she'll have about 4 hours' offlead excercise) so that she's nice and tired for tomorrow...
