Almost every complaint about Yorkshire Terriers comes from expecting a companion breed and getting a working one.
The breed was built in nineteenth-century Yorkshire from small terriers brought south by Scottish weavers, and its job was killing rats in textile mills, mines and stables — confined spaces where a small, fearless, determined dog was the right tool. Selection rewarded boldness, persistence, noise and a complete absence of caution. Only afterwards did the breed become fashionable and shrink further.
The ratings are that history written down. Barking 4/5, because a terrier working underground or behind machinery announces what it has found. Strangers 2/5, because a ratter was not selected to be sociable. Other dogs 3/5, with the classic terrier willingness to challenge something ten times its size. Bold, confident, courageous — those are the breed's own words.
What that means for an owner is that a Yorkie needs training, structure and socialisation like any working breed, not indulgence. The single most common mistake is treating it as an accessory: carrying it everywhere, never asking it to walk, allowing behaviour that would be unacceptable in a larger dog, and skipping socialisation because it is small enough to pick up. The result is a stressed, reactive, over-vocal animal, and the label small dog syndrome describes an owner's choices rather than a breed trait.
A Yorkie that walks on its own feet, is asked for manners, meets other dogs regularly and has been socialised properly is a confident and genuinely charming dog. That is achievable and it is the whole difference.
The Malamute's 3/5 trainability comes from independence rather than intensity, and its 4/5 with strangers means it needs no equivalent socialisation work.
