We all know that our pets age differently from us humans. For average-sized to large dogs, they age about 7 times in a year. For small dogs like a chihuahua, it's about 6 times in a year. If your chihuahua is healthy, he/she may live up to 15 to 20 years. How do you know when your puppy is no longer a puppy because it has turned into a dog? How do you identify when your furbaby is entering the adolescent age? One of the signs is when your female dog starts to fangirl over series... Just kidding! (She has a crush on Rollo of Vikings.) Seryoso sya oh! 😁 Xena is catching up with one of her favorite series. #vikingsfan #XenaTheChihuahua A photo posted by Kye Felix-Pajela (@sleepwalkingscarlet) on Oct 7, 2016 at 2:43am PDT
