Small dogs are often seen as charming companions, but recent research shows they are also surprisingly intelligent.
A study by the University of Montpellier in France found that breeds like Chihuahuas, Pugs, and Pomeranians have larger brains relative to their body size than many larger breeds, giving them impressive cognitive abilities.
