I suppose my answer would have to be the Irish Wolfhound, as I have had three and the companionship, protection, love and friendship they gave was just so amazing. Having said that, I also have had the most beautiful and loving (even calm!) Irish setter ever and now have a lovely little Shih-Tzu, who is full of character , love and intelligence to boot ... and who is convinced he is a Wolf Hound. So, three very different breeds. I think it is what you put into your dog that largely makes him or her the character they become. A lot of love, some early training and good care will make most breeds wonderful companions, but some more than others! I just wish people looking to take on the responsability of sharing their life with a dog would read about the breeds and go for breeds that are suited to their life style, especially if they have children. This way, not so many dogs would end up in rescue centres and the like or just abandoned on the street. These rescue centres do a fantastic and often difficult job, but it is sad that we need them so badly!
Oh, and to Pie & Mash ... how sad you are! I agree with Ratter15. Your comment was soooo unneccessary! Just because you don't like something, there is no need to be rude to others who do! Time to grow up!
