Collie vs Shetland Sheepdog

Two long-coated, sensitive herding dogs that look alike; the Collie is large, gentle and best with children, the Sheltie small, vocal and quicker to train.

Verdict

The Collie and the Shetland Sheepdog share a long, flowing coat, a sensitive and loyal nature, a need for routine brushing and a need for 45 to 60 minutes of daily activity. Both list MDR1 drug sensitivity and collie eye anomaly, and both dislike a noisy household.

Size and voice divide them. The Collie weighs 50 to 75 pounds, is gentle and devoted, earns the top rating with children, and is a quieter dog. The Sheltie weighs 15 to 25 pounds, is the more vocal of the two and learns a little faster, and its profile calls it a poor fit as a sturdy playmate for toddlers. The smaller dog suits apartments somewhat better.

Choose the Collie if

  • You have children and want a gentle, devoted family dog
  • You prefer a quieter dog
  • You are willing to brush a long coat and keep a calm home
  • You have room for a large dog

Choose the Shetland Sheepdog if

  • You want a smaller, smart dog for obedience or agility
  • You can tolerate frequent barking
  • You live in a quiet home with no toddlers
  • You prefer a more compact dog that fits apartment life
