A Smooth Foxker is a Smooth Fox Terrier crossed with an English or American Cocker Spaniel. The resultant breed is one that can be a watchdog, faithful companion, and a fun addition to your family. However, given their Smooth Fox Terrier parentage, they have a strong hunting instinct that can overpower the gentleness of the Cocker Spaniel. A Smooth Foxker requires an experienced owner or family with no young children. They also need plenty of mental and physical stimulation, such as from these activities below.
