can you please help me

Question
I saw this dog when i was out one day and it was absolutely huge. I thought it was a bear on a leash!
It was black and very furry, it looked like a bear of some sort and if it helps any i live in Scotland.

Answer
It was probably either a Newfoundland and more pics can be seen here: http://www.dogbreedinfo.com/newfoundland.htm

Or a Bouvier des Flandres and more pics can be found here: http://www.dogbreedinfo.com/bouvierdesflandres.htm

Both are very large,hairy black dogs
