Oooh, I know this one! The best family dog is MY dog (but you can't have him). Here he is (photo attached)...
This little beauty is one year old and goes everywhere with me (except to see the sheep, who he is terrified of). He's nearly fully grown now, only about another 10KG to go.
Of course, a Newfy is not for everyone. There is a lot of hair. Really, a LOT of hair. I don't notice the drool myself, but do carry several towels in his "go bag" to keep him presentable when out and about. He is quite big and I did have to buy a different car as he didn't fit in my old one. My wife was walking down the lane the other day and said "oh look, the neighbours have bought a dog just like Barney!" On closer inspection, they had in fact bought a new pony. On the plus side, he is the gentlest boy in the world, he quite simply has no aggression at all, and would literally die for my two little boys who he loves more than you would believe possible. He had to have something nasty and very painful done to his undercarriage by the vet, who insisted that he be muzzled in case he bit her (I explained he would be more likely to start reciting poetry than bite anyone). Of course the largest muzzle they had barely fit over his nose and fell off almost immediately while she was messing with his bits. I said nothing and carried on holding him down. Not only did he not bite anyone or even growl, he was most apologetic for all the fuss and gave me (and the vet) a big lick afterwards. Without a doubt, the gentlest of giants and ideal for a family with small children.
