This 4-Year-Old's Best Friend Is A Bulldog

4-year-old Harper doesn't know that she's an only child, because in her mind she's got a sister named Lola- who just happens to be a bulldog.

The two are inseparable-playing dress up together, having tea parties and even hanging out on the bed reading a book, hanging out like sisters and friends rather than pet and owner.

Their amazing, and ridiculously adorable, relationship is documented by their mother, photographer Rebecca Leimbach, who has been sharing photos of the cutest siblings ever via her Facebook page.

Rebecca says it all started as an accident:

Harper came out of her playroom one day and said 'Ta-da!' I turned around and Lola was wearing a tutu, necklaces and a crown, and she didn't seem to mind. I died laughing and grabbed my camera to take a picture... the rest is history.
