HA! Children and dogs are two different animals. And from my experience you lucked out with an easy dog!
Boys are boys. They dont' chew on the furniture, or your shoes. Most climb, run, jump, spill, track mud, eat anything that's not nailed down, etc. But, they can be big, mushy loves too. My tall gangly son just turned 13 and is nearly 6 feet tall. I can hardly keep food in the house and he grows out of clothes and sneakers way too fast. He knocks stuff over without realizing it, he and his friend track lots of mud and dirt in to the house, he hates making his bed and I still have to remind him to take a shower and brush his teeth. BUT - he also cleans the kitchen floor after he and his friends make a huge mess of it (we have a shark hard floor cleaner - lifesaver!), empties the dishwasher, feeds and cats, mows the yard and vacuums the dining room. Contrary to popular belief, boys can be trained! I get wonderful hugs and affection from my tall cute boy (a little awkward still) and he is sweet to little kids and old people. He plays way too many video games, but is also a good athelete.
So match that up with your dog and I think you'll agree that although dogs have their benefits, a son is far better. ;o) Enjoy your boy - they grow up way too fast!
