The Poochi is a mixture of Toy Poodle and Chihuahua. Since the Chihuahua comes in both a smooth coat and a long coated version and can be any color, the coat for this mixture is anyone's guess. It could have the curly coat of a Poodle or a smooth coat, or long coat.
Both breeds are prone to numerous health issues and this will also be true of the puppies from this mixture. These dogs are not recommended for those with children under 10 years old. You should also be sure to socialize these dogs beginning at a very early age as they are prone to be fear biters.
