My dog was growling at a cat walking across the backyard

She runs few steps forward ( within safety of her fenced area, otherwise she'd run inside) while going forward, she stumbles on a branch on ground. Barks more aggressively at cat. Because, the indignity of it all.

Cat just sitting there now looking at her.

My dog now backs up barking and growling. Hits her behind against the sycamore tree and jumps ( i mean jumps) and starts snarling at it. ( the tree)

Ok. She's definitely my dog 😆
