Chihuahuas are so cute, cuddly and friendly. We love our humans and will follow them all over the house. We will snuggle with you, sometimes crawling inside your sweatshirt to be close to you when we sleep. When you get home after being gone, we will jump and squirm for joy because we missed you so much. I am 1/2 chihuahua, so I should know since this is how I act. I'm not sure what this guy is so mad at. I think he must have had a scary time at the vet or had one too many shots. Imagine if he was waiting at the stop of the stairs when you got home after a late night of partying?
