A Chi-Poo, also known as a Choodle, is a small mixed-breed dog that results from crossing a Chihuahua with a Poodle. These dogs can vary in size, appearance, and temperament, depending on the specific characteristics inherited from their parent breeds. They are often small in size and can have a variety of coat types, depending on whether they inherit more Chihuahua or Poodle traits. Chi-Poos are generally known for being loyal, intelligent, and good companions.
