Izzy went through a phase of not like the vacuum a while back, but got over it
TBH I wish she had a little bit of fear in her, but nope, none! Today we went up to see her ponies and she was running after Little Ted and my mums big horse - they legged it when they saw a 'coat' with legs running up to them - but she just doesn't have a an ounce of fear, that I wish was there so she was more wary!
I expect it is a phase, and if like Izzy he will soon be trying to ride the vacuum while you are cleaning!
