Now this is what we call puppy love.

Kaley Cuoco shared an adorable snapshot on Instagram late Sunday night, where The Big Bang Theory star is caught right smack in the middle of her boyfriend, Karl Cook, and her English bulldog, Tank.

"I can't choose," the 30-year-old captioned the photo, along with the laugh-crying and dog emojis.

Cuoco's body language suggests that she might be a wee bit partial to her pup, though according to recent interviews, the actress is absolutely smitten with Cook.

"We met at a horse show, I finally found my horse guy," Cuoco shared on The Talk. "It was very meant to be. We shared a passion for horses and dogs… It's been lovely."

This isn't the first time the animal activist found herself torn between a human and a four-legged friend. Cuoco posted a photo back in June of the cute couple smooching her beloved horse with the caption, "Not sure who I miss more."
