I think it is safe to say that a show type terrier has more hunting instinct than a king charles spaniel or a shi tzu. They cannot be compared. And while a shi tzu may try to chase a squirrel it will not be under my shed fighting tooth and nail with a oppossum or raccoon. A shi tzu doesnt have the dentition of a terrier, wont lock down like a terrier and will give up unlike a terrier. Anyone that would say that a show bred lakeland terrier is equivalent to a king charles spaniel or a shi tzu has not been around a show bred lakeland or has seen what is not the norm.
