About the Collie

The Collie — immortalized by the fictional Lassie — originated in Scotland and northern England as a supremely capable herding dog guarding flocks across rugged highland terrain. Standing 22–26 inches tall and weighing 50–75 pounds, the breed comes in two coat varieties — the iconic Rough Collie with its abundant mane and the sleeker Smooth Collie — in sable and white, tricolor, blue merle, and white colorations. Their wedge-shaped head, almond eyes, and graceful build give them an unmistakable elegance among herding breeds.

Temperament & Personality

Collies are among the most gentle and devoted of all breeds — known for their uncanny ability to sense their family's emotions and respond with quiet comfort. They are exceptionally patient with children and often take on a protective, nurturing role with the youngest family members. While friendly toward strangers, they'll alert you to anything unusual with a distinctive bark — though excessive barking can develop without training.

Pros

  • One of the most naturally gentle and trustworthy breeds with children of all ages
  • Highly intelligent and responsive to training — learn commands with minimal repetition
  • Moderate exercise needs — satisfied with daily walks and yard play rather than intense activity
  • Clean dogs with little doggy odor despite their abundant coats

Cons

  • Rough variety sheds heavily year-round and requires thorough brushing 2–3 times weekly
  • Prone to Collie Eye Anomaly — a hereditary condition affecting up to 70% of the breed
  • Can develop nuisance barking if bored or left alone frequently
  • Sensitive to many common veterinary drugs due to the MDR1 gene mutation

About the Newfoundland

The Newfoundland hails from the Canadian island of the same name, where it was bred as a working dog for fishermen — hauling nets, carrying boat lines, and even rescuing drowning swimmers. Males typically weigh 130 to 150 pounds and stand 28 inches tall, while females are slightly smaller at 100 to 120 pounds. Their thick, water-resistant double coat comes in black, brown, gray, or the striking black-and-white "Landseer" pattern.

Temperament & Personality

Newfoundlands are renowned for their sweet, patient, and devoted temperament — often called "nanny dogs" for their extraordinary gentleness with children. They are calm indoors, deeply loyal, and have an almost instinctive drive to rescue people in water. Newfies generally get along beautifully with other dogs and pets, making them exceptional family dogs despite their enormous size.

Pros

  • Exceptional natural swimming ability and water rescue instincts
  • One of the gentlest giant breeds — outstanding with children
  • Calm and easygoing indoor demeanor despite massive size
  • Highly trainable and responsive to gentle, patient guidance

Cons

  • Heavy drooling — especially after eating, drinking, or exercise
  • Coat requires extensive grooming and sheds heavily year-round
  • Prone to hip and elbow dysplasia, subvalvular aortic stenosis, and cystinuria
  • Shorter lifespan of 8 to 10 years common in giant breeds
