My rough collie, Bijou, is much like Gull is -- Bijou is all about activity and playfulness and being silly and fun. She does herd my kids (I have five kids also, ages 2-12) but with more of a "nose in the back of their knees," rambunctious, chase-about kind of manner, not a "nip with teeth to get them rounded up in a group" kind of way. She also tends to herd my younger ones much more than the older ones, though she likes to jump on my 10-year-old the most -- I think it's because he's most her size when she's up on her back paws "standing" up.

Because my own collie is just over a year, and we adopted her when she was a 14-week old puppy, I can tell you that this first year was hard with having both her and the children to care for. She loves the kids, and they love her, but the smallest ones were a bit fearful when she first came into the house because she was so active and hadn't had any training at all. My pup didn't know she wasn't allowed to race through the house and jump on and off furniture at blazing speeds, and my kids didn't understand that the dog didn't want to eat them! Honestly -- my little ones used to call out, "Bijou's gonna eat me!" It took several weeks to get everyone living together in relative harmony, and we're still working on Bijou not jumping on the kids from time to time - it's simply the puppy in her that gets her going, I have no doubt in another year or so she'll be much better behaved, and of course the kids will be another year older/taller as well.

That all said, I do feel that a collie can be a magnificent choice for your family if you're able to adopt an older dog and know a bit more about temperament/activity level, etc. Bijou is enormously tolerant of the kids and always has been, even as a puppy. The kids are as careful as kids can be with Bijou, but they tend to give love in a big way which means lots of hugging and occasional tugging and joyful snuggling. It's really beautiful! My two-year-old daughter often throws her arms around Bijou and says, "I love my Bijou!" and Bijou looks at me with her big brown eyes as if to say, "Well, this sure beats living alone in a barn back before you brought me home!" Everyone feels good having her as part of our family

Best wishes -- you've received very good advice and I agree that a trial run is the best way to go and if you're unable to do that, then adopting a dog with a known history and temperament is most important. I've always believed that the temperament of an individual dog is a more important consideration than a specific breed in and of itself.
