Side-by-side comparison of two popular breeds — temperament, exercise, grooming, lifespan and common health issues. Use it to decide which breed fits your home.
The Cairn Terrier (6–7 kg, 13–15 years) and the Scottish Terrier (8–10 kg, 11–13 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.
Both breeds have similar energy demands — Cairn Terrier tips slightly higher but neither is a couch dog.
Both have manageable grooming routines — the Scottish Terrier demands slightly more, but neither needs daily fuss.
