Hi and welcome.
Be sure to check out all the Stickys in the General Section as I see you are researching to buy a Newf puppy. Huge amount of good advice there.
Please let us know if we can help with any questions you may have.
Like Angela mentioned, there is a TON of fantastic info in the stickies about determining if a Newf is the right breed for you and helping guide you on selecting a responsible breeder! Welcome to the forum.
