The Cardigan Welsh Corgi is a small, generally cute dog breed weighing an average of 30 to 38 lb (13 to 17 kg) and with a height of about 10 to 12 inches (26 to 31 cm). It is one breed of two known dog breeds within the group Welsh Corgis that originate from Wales, more specifically from Cardiganshire (as the name implies), and it is also one of the oldest herding breeds. It is a very small dog, very low, with upright ears, a long tail and an even longer body. The old American Kennel Club used to call it an Alsatian on short legs. The main fur colours include brindle, black, red, fawn, sable, and blue merle, usually together with white markings. They don't shed much hair and don't require much grooming either. They are said to originate from the Teckel family, also known as Dachshunds, and have been in existence in Wales for over 3000 years now. The Cardigan Welsh breed was first registered with the AKC in 1935.

The Cardigan Welsh is a very affectionate dog and it fits will within families. The occupation it was bred to do, namely herding cattle and hunting smaller animals, is something the animal doesn't forget easily, and it has a tendency to nibble on people and to circle around them to keep them in place, it may sometimes chase after people who move quickly or smaller animals that run away, but it is in general not very aggressive at all. They like barking as well, and are very alert so they make very good watchdog.

The Cardigan Welsh has a general lifespan on 12 to 15 years, and the most common health issues include thyroid problems, spinal problems, HD, PRA, and obesity. In general they are a healthy breed as long as they receive their daily dose of exercise. It is also good to note that parents of a Cardigan Welsh Corgi puppy should have both OFA and CERF certificates. The Cardigan Welsh breed is very intelligent, eager and responsive, and should be no problem at all to train. Training it to rid itself of its' nibbling tendencies isn't anything impossible either, and it is suited for both the experienced and un experienced dog owners. They have lots of energy, and need a regular daily dose of activity to stay healthy. They are reserved and polite towards strangers, and may get along well with other pets if accustomed to them.
