Three small terrier breeds share Highland roots and a knack for vermin hunting, but their looks and temperaments diverge more than newcomers might expect.
A Shared Working Past
Each of these breeds was developed to root vermin and small game from rocky Highland terrain, which is why all three share a compact, low-set build and a strong digging instinct that persists in companion dogs today.
Temperament Differences Worth Knowing
The Scottish Terrier tends toward dignified independence, the Cairn Terrier stays close to its spirited working roots, and the Westie splits the difference — confident and feisty but generally more sociable than the Scottie.
Choosing Between Them
Coat color and grooming style are often the deciding factor for prospective owners, since temperament and care needs across the three are broadly similar — the individual dog’s personality still matters more than the breed label alone.
