Here's a formula you need to know: dog + proposal = irresistible viral video.

Don't believe it? Look at the clip above, where a man surprises his girlfriend with a puppy. She's already in love with the little critter when her beau encourages her to "read her name tag." That's when the woman realizes getting a dog is going to be the second biggest thing to happen to her on this day.

Her boyfriend gets on bended knee and pops the question, while also taking the ring he kept around the dog's collar.

The woman is bawling like, well, like a woman who just got an adorable puppy and engaged in a one-minute period.

Good luck trying to top all these emotions on their wedding day. Unless, of course, he plans to surprise his bride with a whole little of puppies.
