Cardigans are less sociable and more territorial than Pembroke's. Good with other non-canine animals and with other Corgis, but can be combative with other dogs. Several of these brave dogs have lost their lives defending their homes, as they were too small for the situation. They sometimes attempt to herd people by nipping at their heels, although they can be trained not to do this. The Cardigan is a good alarm barker and some tend to bark a lot.
Males can be aggressive with other males, particularly if a bitch in heat is in the vicinity.
Some are prone to PRA and glaucoma. Do not overfeed this breed, as it tends to gain weight easily. Living Conditions Good for apartment life. They are very active indoors, and will do okay without a yard. About 12-15 years.
