Generally a well-balanced Scottie dog should weigh from 8.5 to 10 kg (19 to 22 lb) and a female from 8 to 9.5 kg (18 to 21 lb). They were supposed to have inspired the name of his Regiment, The Royal Scots, 'Dumbarton’s Diehards'.Scotties, while being described as very loving, have also been described as stubborn. They are sometimes described as an aloof breed, although it has been noted that they tend to be very loyal to their family and are known to attach themselves to one or two people.It has been suggested that the Scottish Terrier can make a good watchdog due to its tendency to bark only when necessary and because it is typically reserved with strangers, although this is not always the case. They have been described as a fearless breed that may be aggressive around other dogs unless introduced at an early age.
