Samoyed (dog) The Samoyed ( or ; Russian: Самоедская собака or Самоед ) is a breed of large herding dog, from the spitz group, with a thick, white, double-layer coat. It takes its name from the Samoyedic peoples of Siberia. These nomadic reindeer herders bred the fluffy white dogs to help with the herding, and to pull sleds when they moved. An alternate name for the breed, especially in Europe, is Bjelkier.
Clumber Spaniel The Clumber Spaniel is a breed of dog of the spaniel type, developed in the United Kingdom. It is the largest of the spaniels, and comes in predominantly white with either lemon or orange markings, but can sometimes be either brown or lemon predominantly. The name of the breed is taken from Clumber Park in Nottinghamshire where the breed was first developed. It is a gundog that specialises in hunting in heavy cover. They are gentle and loyal, and can act aloof with strangers. They have several habits which could be considered disadvantages, including a constant shedding of its coat and snoring.
