Hi! Glad to have you here. A bear??? I think our Riley would probably faint
if he saq a bear! lol You have a lot of DOG on your hands with a Berner and a Newfie! We have never had a Newfoundland, but talked about it over the years. They are beautiful dogs! The few that I have met had a lot of the same personality traits that our Riley does.
Would love to see some pics of both. Again, welcome to the site.
