However, this is not the only nose characteristic that the sussex spaniel has. (B) The sussex spaniel has a rounded face and a straight nose. Its muzzle/chin is square with rounded sides. (C) It has heavy eyebrows, which are the key feature that creates this frowning expression. [substeps] The dog's eyes are large and hazel colored, with a soft and passive expression.
