The Breed Standard and Temperament of a Cairn Terrier
According to Vanessa Richie's book "The Complete Guide to Cairn Terriers," The average Cairn Terrier is between 9.5 and 15 inches tall. Weight is on average between 13 and 15 pounds. The AKC indicates that standard markings include black ears, black around the mask or face, and black markings.
The Cairn Terrier can come in a variety of different colors. According to the AKC, these include:
- Brindle
- Cream
- Gray
- Gray Brindle
- Red
- Red Brindle
- Silver
- Wheaten
- Cream Brindle
- Black
- Red Wheaten
- Silver Brindle
- Wheaten Brindle
- Silver Wheaten
However, a Cairn Terrier cannot be white, as this is the color exclusive to the similar breed of the West Highland Terrier.
Cairn Terriers have a true terrier personality. They are friendly with other dogs and amazing family dogs. Cairn Terriers insist on being part of family activities. They need to live indoors with their families, rather than outdoors in dog houses. They not only have a deep love and loyalty towards their families, but they are also well-known for having a great affinity for children. Cairn Terriers are friendly and curious, eager to interact with people they meet. They do not do well when left alone for long periods of time, as some may be prone to digging and barking.
Cairn Terriers are intelligent and love positive reinforcement training, but also have an independent stubborn streak. They have a high prey drive and therefore require a fenced in yard and leashed walks.
Cairn Terriers are very curious dogs, and love to go along with their humans, whether on a day trip or on vacation. They love parks and outdoor spaces. Some stores such as home improvement stores, pet stores, and craft stores welcome dogs. Some outdoor malls also welcome dogs. These can be fun places to take your Cairn Terrier. Always check with individual stores about their dog policies before bringing your Cairn Terrier to a store.
