My oldest two are 15 and 12, but neither likes dogs. And my 4-year-old would probably die of fright.
Golden retrievers are nice, though. We have one up the street who meets us on the sidewalk when we're out, and politely sniffs and wags.
My 18 year old loves the dog (and of course the dog worships her) but my 15 year old prefers cats.
He's going to wind up with some dog duties, though, now that the 18 year old is off at college . . . as my husband tells him, it's just the price you pay for three squares and a warm place to sleep . . .
