Personality
General Temperament
Collies are smart, enthusiastic dogs. They are highly attuned to their owners and always seem at the ready for a game of fetch, canine sports training, or a long walk. Though devoted and eager to please, they are also known to have a stubborn quality at times. Intolerant of being alone, they are likely to become nuisance barkers or develop destructive habits if left alone excessively.
Family Life
Are Collies Good with Kids? Collies are loving and gently protective of children, but they should always be supervised around kids. Owners often share stories about how their Collie will 'herd' a toddler back to the family if they stray too far.
(Note: Every dog has a unique personality and distinct life experiences that affect his disposition. As a rule, adults should always supervise playdates between kids and their four-legged friends.)
Are Collies Good with Other Pets? When Collies are well socialized from an early age, they are generally welcoming, respectful, and playful with other dogs, as well as cats. They can be standoffish with animals they don't know but, given time, will usually tolerate their presence.
Protective
Collies are protective of their 'flock,' which at home means their family. They will bark loudly to alert their owners when people they don't recognize approach the house.
Are Collies Good Guard Dogs? Collies are attentive watchdogs, who will let the household know when people are coming to the door or just walking past.
Energy Levels
The Collie is a highly energetic breed. With enough exercise throughout the day, they will settle down and enjoy quiet time with their families at home.
