Prospective buyers should visit dog shows, check the
Newfoundland Club of America (link to Newf club) for
breed information and the names of responsible breeders, and should never, ever buy a puppy from a breeder who does not test both sire and dam for hip dysplasia and heart problems, allow puppy buyers to visit with
adult dogs, and answer questions about the
breed and his
breeding program.
From inspection of the growth components in Table 1 and the dendrogram in Figure 2, we see that the separation in the cluster analysis occurs principally at
adult maximum body weight, which drops abruptly from 43.3 to 28.1 kg between the
Newfoundland and Labrador Retriever
breeds.
