They weren't ticks, they were just knots of hair, we managed to untangle one but the other is impossible, my mum's taking her to get groomed when they get home. She's got another one now, I wonder if it's just because her hair is so curly?
Glad it wasn't anything serious. I work in Groomers conditioner with my fingers behind Dougalls ears, that seems to help a lot. I will give the cornflour a go, never thought of that!
