I dont envy you trying to get her clean, We have stables and am finding it hard. I would love to bath my boy saturday but if it carries on like this will be way to cold
Do you have any rugs with neck on, fear this may be you only hope to keep her well covered.
I am taking my boy, I am useless at Geography and said oh we could go to that show, entered then found out its 124 miles away lol
Unless you can keep her in the night before the show I'd get up early Sunday morning and bath her in warm water and then use a thermotex to dry her. Will take a few hours so if she is good with a hair dryer then this might be another option
