Make sure you have thoroughly researched the Breed. Whilst Newfoundlands can make excellent pets, they are not the breed for everyone. They can be dirty, slobbery, often wet and shed hair everywhere. As youngsters they can be boisterous and sometimes destructive. At any age they can be smelly if not regularly bathed and groomed - Newfoundlands need time and effort to keep in good condition. They can be expensive to feed and, as with other giant breeds, vets fees can be astronomic and insurance premiums similarly expensive.
There are three Newfoundland Breed Clubs in the UK (as recognised by the Kennel Club) and two in Ireland. Their web sites provide excellent information about the Breed.
Dog shows also provide the opportunity to see the dogs and talk to owners. Please remember Newfoundlands at shows are usually well behaved and very clean as they are being presented for judging but living with one can be a very different experience! Dates of Championship shows can be found on the UK Newfoundlands Info web site and a regularly updated list of Open shows where there are classes scheduled for Newfoundlands can be found on the Southern Newfoundland Club web site.
Newfoundland Working Events and Fun Days provide an excellent opportunity to chat to other owners. Information is available about these events on the Breed Clubs' web sites.
Contact reputable breeders (members of the SNC Better Breeders Scheme have profile pages with their contact information on this web site) and talk to them to find out more about the breed.
