Do you like Chihuahuas? Today you'll discover five facts about them that you probably didn't know. Pay attention to number three. 1. Big Brain Chihuahuas have the largest brain in relation to their body size of any dog breed. This doesn't mean they're the most intelligent, but they do have a great capacity for learning. 2. Open Fontanelles Some Chihuahuas are born with a soft spot or fontanelle on their skull that in some cases doesn't close completely. It's important to handle them with care, especially when they're puppies. Although in many cases the fontanelle closes over time, some Chihuahuas keep it for life, which makes them more vulnerable to injuries in that area. 3. Toltec civilization it's believed that the ancestors of the Chihuahua were the Dichichis, small dogs bred by the Toltecs in Mexico over 1,000 years ago.
