Shetland Sheepdogs are known for being generally more vocal than most other dog breeds (key word: generally).
Of course they are. They're very intelligent! You'll be glad to find more about them. Just click on: http://dogtime.com/shetland-sheepdog.htm...

Up to 63 days on average.
13-15 years

No, absolutely not. Shetland Sheepdogs generally have a height of about 13-16 inches, whereas Shetland Ponies have a height of between 28 and 42 inches.
