Thanks Vida and Jazzy.
I put her head collar on for the first time today. She stood good as gold whilst I put it on over her nose, it was when I tried to adjust the buckle that she tried to take off.
She had it on for just over an hour, she didnt seem bothered by it at all, which I'm glad about, I imagined it being really difficult.
She's been very boystrous(sp?) today, she tends to rub round you like a cat does, and she loves her neck being stroked. She was following Ellie all round the field and then doing a little bronc or rear.
I know she's being playful, but I've told Ellie to be extra careful, especially now she is getting so strong.
Any advice or suggestions for the days ahead, what I need to be doing etc will be greatly received and appreciated.
