Terriers are all heart and won’t back down from a bigger dog. You have to admire the kamikaze spirit in them.
We have a three and a half pound Maltese, and the whole planet should rejoice that he’s not 90 pounds and four times larger in size: I’d let him outside to potty and he come back later on carrying human body parts and automobile tires in his mouth, probably.
Utterly fearless beast with a strict sense of guard dog duty and an enormous ‘little guy’ chip on his shoulder. Flies into combat at the drop of a hat.
I have a mixed terrier and she is just as you said - feisty and won’t back down, regardless of the size of the other dog She tried to take on a huge German Shepherd last week. That do would have eaten her for lunch, but she stood her ground. Bless her heart. Fortunately, that over-sized shepherd wasn’t hungry.
