I just realized that he must have been separated from his mom before 8 weeks. I know that happens sometimes with rescues (and I suspect that my boy may have been), but it's far from ideal and it's something you should be aware of. For example, puppies learn bite inhibition from their moms and littermates when they're young, so you may have your work cut out for you if he's a nippy puppy (labs are especially mouthy). My guy was nippy, and it was difficult for me sometimes, so absolutely supervise your children at all times (though you should anyway). Also, socialize, socialize, socialize as soon as you get him. Before he has completed his his shots, try to have play dates with vaccinated dogs you know with good temperaments. Take him new places every day. They say puppies should meet 100 people in 100 days; the more, the better. Puppy classes are wonderful, for you and for him.
Very good advice! Yes, I assume he was separated from his mom early. He has been with his brother tho and his foster mom has 6 other dogs, so he has been well socialized with other dogs.
I read about making a "hurt" sound if they put their teeth on you, so they learn not to do that.
Also, he will be at my husband's business during the day so he will meet lots of people every day, so that is good! We are also taking him camping with us next weekend and I'm sure he will meet lots of people, kids, dogs there too.
And we will look into puppy classes too. I think that would be a great thing for my older child to get involved in also (well, he may need kid classes for obedience too, but that's another story )
