Training

Cairn Terrier
- ** Positive reinforcement with high-value rewards (food/toys). Repetition bores them; keep sessions short and novel.
Australian Shepherd Considerations
Aussies control movement by nipping at heels. In a family setting, they often attempt to "herd" running children, bicycles, or cars. This is not aggression, but a hardwired instinct that can be terrifying for toddlers and a liability for owners.
This breed has an intense need to be with their people. They do not tolerate isolation well. Leaving an Aussie alone for 8+ hours a day frequently leads to severe separation anxiety and destructive chewing.
Unlike the "love everyone" Golden Retriever, the Aussie is naturally reserved with strangers and protective of their territory. Without extensive socialization, this reserve can escalate into fear-based reactivity or aggression toward guests and strangers.
Cairn Terrier Considerations
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.
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.
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.
