$1200 is actually cheap for a Newfoundland puppy!!
You need to read all the Stickys at the top of General Forum about breeders, buying puppies etc before committing.
You need to get copies in your hand from the breeder of all health clearances done on both parents, these should be official OFA certificates.
Newfs are prone to heart problems SAS as well as hip, elbow dysplasia.
Please, please ask loads of questions here and to breeders.
The breeder should register the litter, you are entitled to AKC registration papers.
Don't be fooled by pretty, colourful, glowing websites, you can PM any of us here if you are interested in a kennel. We want the best for you.
I have read some horror stories on FB over the last few months about people getting puppies and after the transactions are completed, the breeder doesn't want to know.
I feel sad that some new people are treated this way.
