Leonbergers mate. From Leonberg in Germany. Incredibly friendly dogs. High maintenance apart from the cost though as they want your attention all the time.
If I had to have a dog for protection purposes, I'd just get a pair of Tibetan Mastiffs, then sit in my house wondering why my mum hasn't popped round for several weeks and where the dogs got all those bones from. I don't though, I just walk my little soft as **** cavapoo and I carry a little 'tool' with me just for emergencies, in case one of the local div kids has let his hard man dog off it's leash. The circumference of instant attack before thinking will widen, fairly soon as well. Take no chances, it's just a dumb ****ing animal as far as I'm concerned.
