Hi
I have a 6 month old brown Newf pup and MiniPeace has pretty much covered the basics ;)
I would wholeheartedly advise making contact with the breed club and being put in touch with someone who will allow you to visit their full-grown Newfs so you can get an idea of what you're letting yourself in for. Newf puppies are the cutest things ever but the 10 stone slobbering, shedding adult who positively has to sit on your knee is a world away from the cuddly little teddy-bear pup you bring home at 8 weeks of age! Sadly, many Newfs end up in rescue because their owners were not prepared for the reality of living with an adult Newf.
As Minipeace has said, they are not a breed for the houseproud. Their natural state is wet and they can seek out a muddy puddle in the driest of weather. They will then return home and redistribute the contents of said puddle from their coat to your walls and furniture. We have Newf-proofed our house...leather furniture, hard floors etc...everything must be easily wipeable!! ;) And somehow you will find Newfie hairs in the butter and every yoghurt tub you open. Not to mention the fact that one shake of the head is enough to coat most of the ceiling in drool

Basically, they are not the breed for the easily grossed-out!
Having said all of that, they are the gentlest, most loving breed I have ever come across. We have waited a long time to be in the position to get our first Newf and we're already planning for more (although not for some years). They are addictive and you'll find very few people can stop at just one! Don't say you weren't warned :D :D
