Golden Retrievers are sweet, friendly family pets who always want the best for everyone – right? If you think that, you should take a closer look at Frankie the mischievous dog.

A recent viral video shows the baby getting upset while Golden Retriever Frankie wags his tail back and forth.

It doesn’t take long for suspicion to fall on the dog, who looks genuinely grumpy for a Golden Retriever.

His owner quickly notices that Frankie has something in his mouth.

Grumbling, she reaches in and pulls out her daughter’s pacifier.

But something still isn’t right. Frankie continues to look angry, and his mouth still seems full.

So she reaches in again, hardly believing her eyes.

"Oh, you have two?!" the woman exclaims as she pulls a second pacifier from the animal's mouth. "Frankie, that's a bad boy!"

But this theft is just one of many in a string of brazen robberies.

Another video shows that this is a routine occurrence in their household.

"Me thinking I was capturing a loving moment between Frankie and his baby sister... But he was just waiting for the perfect opportunity to steal her toy," reads the onscreen text.

In that clip, the pup indeed shows his naughty side once again.
