Chihuahua

Cairn Terrier Considerations

challengePredatory Aggression

This breed possesses a (see Section 15). They were bred to bolt, chase, and kill vermin in rock piles (cairns). This means they cannot be trusted with hamsters, gerbils, rabbits, or birds. This is not a training issue; it is a genetic feature.

challengeAlert Barking

Cairns are vigilant watchdogs. They will announce every delivery truck, squirrel, and passerby. In shared housing (apartments/condos), this can lead to noise complaints if not managed early.

challengeDigging

Their large front paws and strong nails are designed for excavation. A bored Cairn left alone in a yard will landscape it, often digging under fences to pursue prey.
