A rabbit, or kaninchen (the German word for rabbit), Dachshund is a smaller subset of miniature Dachshund. While a miniature Dachshund is defined as being 11 lbs or under at 12 months of age, the rabbit Dachshund is under 8 lbs, and has a chest circumference less than 12 inches, at 1.5 years old. While the miniature Dachshund is recognized by every breed registry around the world, the rabbit Dachshund is not.
