What size is a full-grown Chiweenie?

The size of an average full-grown Chiweenie can range from five pounds to 20 pounds, standing seven to 11 inches tall. Chihuahuas are small dogs who weigh as little as two pounds, but Chiweenies can be much larger because standard Dachshunds can reach a whopping 30 pounds. Some Chiweenie puppies may be larger or smaller, depending on whether the Chihuahua was bred with a Miniature or Standard Dachshund.
