The content of some of the albums has changed over the years in any case. I learned that when the Tintin albums began to be published in the United States in the 1950's, some of the pages were left out because they were too controversial in the depiction of alcohol use and the mixing of the races. It was only after Hergé changed some of the pages that the American publisher brought out complete editions.
Yes, dogs of that type are called "chiens Milou" - I see ads for them at kijiji and other sites. Milou is adorable.
It is funny how things such as alcohol consumption would have been censored in the US, although Haddock's abuse of drink was certainly not glamorous.
Early Tintins contained racial stereotypes that would be unacceptable nowadays, though some of the author's own ideas seemed to have evolved, not only because of publisher insistence but also his own encounters with people from other cultures such as his Chinese friend Chang.
