Though she didn't show it as a little babe, our Holland can be pretty feisty. Here she is growling at dad. Granted, she is boxing the guy. Maybe a little growling will help her win.
Holland also practices safety by wearing headgear. The headgear weighs as much as her head...so I don't know how safe it is, actually.
And I love how Brian ducks and covers, giving Holland the idea that she is pretty fierce.
