This adorable Sussex Spaniel has actually been called ‘placid,’ which basically means that it’s incredibly tranquil and serene. And considering how small it is, you can take this adorable and docile pup with you wherever you go. However, considering it’s still part of the spaniel breed, it still has a tendency to have some excitable energy, loving to howl and bark when they’re outside, but thankfully they’re still normally relaxed and steady when they’re inside. And despite their rather somber expressions, they are actually a very happy and cheerful breed.
