Bred to be herders, they are well-proportionate with a lean, muscular, and athletic physique. With medium-sized oval eyes and large ears that fold on the top frontward, Collies have a proud appeal and noble stance. Collies have multiple colors, often a combination of sable being dominant and black, tan, merle, or mahogany with white chests and random patterns.
They tend to be very intelligent and display fierce devotion but have excellent temperaments and highly developed personalities. A collie will consider you their shepherd and create a deep, loyal relationship with you, but they tend to get bored when left alone and bark incessantly.
Rough collies boast a more laid-back persona, whereas Smooth collies are more energetic and outgoing, although both varieties display high-strung tendencies. This dog is not aggressive and, as such, makes a great family member and a natural people pleaser, as well as being very kid-friendly.
Collies make for good therapy dogs and guide dogs for blind people as they are innately intelligent. Due to their protective nature, collies are good pet-sitters and are instinctively curious.
