* Data Collection: There's no single, centralized registry for all dogs in the US, so accurate statistics are hard to come by.
* Rarity Varies: What's uncommon in one region might be more prevalent in another.
* Breed Definition: "Uncommon" can be subjective. Some breeds are recognized by major kennel clubs but might be rare in general, while others might be hybrid mixes without official recognition.
However, some breeds are often cited as being among the rarest in the US:
* Azawakh: This sleek, African sighthound is known for its athleticism and unique appearance.
* Norwegian Lundehund: With six toes on each paw and the ability to turn its head almost completely around, this breed is a fascinating but rare sight.
* Komondor: This Hungarian sheepdog boasts a distinctive corded coat that resembles dreadlocks.
* Otterhound: This large, water-loving hound is known for its webbed feet and otter-like tail.
* Xoloitzcuintli: This ancient Mexican hairless breed comes in three sizes and has a devoted following.
Keep in mind: While these breeds might be rare, their numbers can fluctuate over time depending on factors like breeder interest, popularity trends, and health concerns.
