Puli is a medium-small breed of dog known for its long, corded coat. The tight curls of the coat, similar to dreadlocks, make it virtually waterproof.
Puli comes in white, apricot, and black. It generally weighs around 22 pounds (13 kg) and is about 16 inches (42 cm) at the shoulder, however males have been known to reach 45 pounds and females over 30 pounds. The coat needs considerable grooming to keep its cords clean, neat, and attractive, or it needs regular trimming to a short coat for lower maintenance, although the corded coat is what attracts many people to the breed.

The Puli does shed though less than some breeds, but the cording of the coat keeps much of the shed fur from leaving the dog, making it attractive for dog owners with allergies.
This breed is very energetic, intelligent and makes for a good watchdog and family pet.
