Just remember--she wasn't just a loving dog, she was a loved dog.
I can't say enough good things about a boxer, especially with children. My husband wants me to point out, however, that if anyone wants a dog that will just lie down and relax... get something else! Boxers are very high energy, as you've no doubt read. With children, I'd say that's a plus. Mine were (and our remaining one is) still like a puppy. My only real concern with mine was that they jumped up a lot (they can be trained out of this, I'm sure, but I was never successful at it). So the only real risk to children was that mine would bowl them over... then they'd lick them as much as possible! So if there were children (or adults) they didn't know, the excitement would take over and they'd overwhelm you with love. But they were wonderful with our son, especially given that they were six when he was born and had not had daily exposure to children before. The funniest thing they would do is give "boxer hugs." If you are kneeling or at their level, they will jump up and actually get their paws around your neck (the better to reach your face for licking). I'm so glad my dog had that time with my son, because I think they were always disappointed not to have their own child before... they used to have to make do with neighborhood children. My girl loved having her own little boy. She patiently withstood all the toddler poking and prodding and just loved him completely.
