What can be done?
I spent ages standing in the rain outside with 8 week old madam today, and she refused to pee. The minute we got indoors she peed on a blanket, she ran indoors so fast it must've been quite desperate! - I was still walking through the door with my umbrella as I saw it happen!
Yesterday went so well, with dry weather we could keep the door open and there was only one accident all day long.
But I can tell she HATES the rain!
My last puppy also didn't like the rain but she would at least go quickly then rush back indoors! 
Is this just a matter of patience or is there a technique I'm missing here?
