The Our Life Adventures YouTube channel has shown a video of a young horse named Annie who believes she is a dog. The video shows Annie refusing to leave the house and lying on her side on a living room rug when it's time to go outside. Despite this, her mom carries her out in her arms and expresses her love for the horse. The footage was viewed as a challenge to tell Annie she is not a dog, but a gentle reminder. The horse's age is not specified, but horses grow rapidly and can gain as much as two to three pounds a day in the first month of life.
