I have 3 dogs I would recommend for a family, a golden, swiss mountain dog and a st, bernard. My family use to breed/raise goldens so have grown up around them. I owned my girls daddy and my Zoey. My male was as dumb as a post but probably the best dog I have ever had. It was to bad he was hit and passed away before his time. Now my Zoey is great! I have had her since she was born and only have one major issue with her. She loves men. She threw me under the bus for my SO lol. Ever since my son was born she has never left his side. She is truly his best friend. She is 14 though and with her age have come some problems. Because she can't hear very well while she is sleeping you can't let babys startle her or she will snap. She gets grouchy with my other girls and think she is the boss so when one gets in trouble by mom she thinks that it is her job to enforce the punishment. This always ends with her getting hurt rather then the other 2.
My swissy is about 4 now but she will take a beating. I watch a 2 year old that will crawl, grab, pinch, pull, sit and everything else to her and she just lays there with a little smile on her face. The only problem we had with her was that it took her about 3 years to be potty trained fully. That is a breed standard though. If you don't want to deal with 3 years of potty training then dont get a swiss!!
My youngest is a 100 pound 11 month old St. Bernard. She is like no puppy I have ever had to deal with. She really is a gentle giant. She is everything I have ever heard about this breed, smart lazy, loves kids, and protective of her family. She would never do any bodily harm to anyone but with such a big dog and such a fearsome bark it would make anyone think twice before they entered my house. Also she is the biggest lap dog ever!! I will put a picture of her trying to sit on the chair with my SO. I love it!! I can't wait to see what it will look like when she reaches her full weight of 175-200 pounds
My girl is a very easy keeper. She is the german standard of the breed, which is the true standard, with short hair or smooth coat and a dry mouth. This breed of bernards I think is the only way to go.
I hope some of this helped!!
