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.
Cavalier King Charles Spaniel Considerations
This is a "Velcro dog" in the truest sense. They were bred to warm laps in drafty castles and have not lost this biological imperative. They cannot be left alone for standard workdays (8+ hours). Isolation leads to profound distress, destructive chewing, and incessant whining or barking.
While they are toys, they are still spaniels. They retain a prey drive that can be triggered by birds, squirrels, or butterflies. This "arrested" predatory sequence means they may suddenly bolt into traffic if not leashed, despite generally good recall.
