Since a Chi-Pom puppy results from the crossing of two of the tiniest toy dogs recognized by the American Kennel Club -- the Chihuahua and the Pomeranian -- your little love bug will remain pretty small. This mix is also known as the Pomchi, Pomahuahua and Chirianian. Chi-poms appear in all canine colors, and multi-colored dogs are common. The cross can be either single-coated like the Chi or double-coated like the Pom.
The smallest of the toy breeds, full-grown Chihuahuas don't exceed 6 pounds in weight. While well-balanced, Chihuahuas are somewhat more fragile in appearance than Poms. Chihuahuas are extremely devoted to their person.
At maturity, Pomeranians should weigh between 3 and 7 pounds, ideally weighing between 4 and 6 pounds, according to the American Kennel Club breed standard. Although little, he's compact and sturdy in appearance.
No matter which side of the family your Chi-Pom takes after, figure that he'll mature at 6 pounds or less. That makes him a pretty portable pet. Chihuahuas are usually aware that they're small and vulnerable. That's not necessarily the case with the Pom, who thinks of himself as a big dog in a little canine's body. If your pup has the Pom temperament, you might have to protect him from taking on bigger dogs who cross his path.
