Helen and Max

James serenades Bruce



Bruce (Bruschetta) is a miniature pony/Shetland who is full of mischief and seems to like music! She lived on the property next door before she adopted us. We didn't know her name and we were told she was a gelding so we called her Bruce. Then one day she swished her tail and became Bruschetta....
