Internet viewers have deemed a dog’s reaction to trying sparkling water “valid” as the confused pup appeared shocked and confused.Nellie, a miniature bull terrier, lives in the U.K. with her owners, who have a TikTok account dedicated to her: @nellie_the_mini_bully. This details the adventures of the 12-week-old pup, from getting the zoomies to taking naps in the most-comfortable spots in the house.Now one recent video has catapulted Nellie to viral fame, as her owners documented her trying sparkling water, rather than still. In a clip viewed close to 5 million times since being posted on June 24, her owner places Nellie’s water bowl on the ground, with the puppy wagging her tail in anticipation.But once she leans over and takes a short drink, she immediately realizes something’s not right. Nellie first walks away from the bowl, before designating it her enemy—and she jumps, barks and growls at the suspicious water as her owners burst out laughing.Just to be certain, though, Nellie takes another short drink—and, with her suspicions confirmed, she continues jumping and barking at the bowl. The video caption reads: “Why it spicy.”And TikTok users loved it, awarding the clip more than 1 million likes, as one user called Nellie’s reaction “reasonable” and another called it a “valid response.””Seriously sparkling water tastes like static tv,” one viewer posted, as another added that “sparkling water tastes like an email.” And as a third person summed it up: “Bro drank the water of uncontrollable rage.”Some commenters worried Nell could get sick from drinking sparkling water. Veterinarian Dr. Gary Richter, author of The Ultimate Pet Health Guide, told Rover that, while carbonated water is “OK in a pinch,” he would not recommend large amounts of it as there is a “rare” chance it could lead to gas buildup.Having still water available for puppies is vital, as it facilitates the metabolic process and regulates a puppy’s temperature, according to the American Kennel Club.When house-training a puppy, owners may choose to remove water overnight to prevent accidents, but it should be readily available throughout the day.Newsweek has contacted @nellie_the_mini_bully via TikTok for comment on this story.Do you have funny and adorable videos or pictures of your pet you want to share?
