It's not uncommon for a soccer fan to have a strong reaction when he or she hears the name "Lionel Messi."
The 26-year-old Argentine is, after all, one of the best players in the world and a four-time Ballon d'Or winner.
Apparently, it's not just humans that are turned on by Messi.
In a new viral video, a dog gets worked up just at the sound of Messi's name. The pooch has no reaction to hearing the words "Cristiano Ronaldo," Messi's Real Madrid rival. But upon hearing the name of Messi, the dog snarls and shows its teeth.
The dog has a similar reaction when it hears the name "Sergio Busquets," another of Barcelona's star. So it appears that this dog is squarely in the Real Madrid camp.
Perhaps it is sarcasm or a matter of interpretation, but the YouTube title is "Dog Loves Lionel Messi!" In either case, there is no question that the dog responds in emphatic fashion.
The video has 100,000 views in less than a week.
This isn't the first time we've seen an intense rivalry extend to dogs. In Nov. 2012 a dog named Dexter became a viral sensation after he refused to eat a piece of jerky is associated with the Cowboys.
