This dear lady...

...behaved like an asshole today.

I took her horse-riding as she loves to join us, and so that she doesn't have to stay at home alone.

When I was trotting and going for a canter, she barked so madly and jumped at Boy's face several times in such a fierce way, that he shied away. He could have hurt himself badly, but we were lucky.

I have tried to teach her so many times and in such different ways not to do it, but there is no use. I reckon with her breed she just gets into that crazy unstoppable mood. 

Means she needs to stay at home in the future when I am horse-riding, and I cannot help her feeling sorry about herself then. A shame.
