'Snoot Challenge': Adorable and Sometimes Confused Dogs Try Their Hardest to Compete

Dogs everywhere are getting in on it — or not.

The “Snoot Challenge” is now taking the internet by storm. 

The challenge involves dog owners placing their hands in the shape of a circle or a heart and testing whether their dogs run up and put their noses in the space. 

Many dogs, small and large, automatically do it. 

Others dogs hilariously failed.

And dogs aren't the only ones joining in. Some are testing their feline friends too. 

It's not clear who started the challenge, but it has gone viral on social media, with thousands of people participating.
