If you are asking about shedding, it will probably bother you. It doesn't bother me. I only vacuum weekly and it's pretty bad by the end of the week! (We have another small dog as well.). It helps to brush the dog a lot, a job you can give the kids. Not sure if anyone has mentioned this group yet, but we have had 2 rescues from there, and they were wonderful. We now have a golden we got as a puppy. That was frankly a ton of work, so maybe start with an adult, ideally one only 4-6 so you have several good years with it. The rescue process takes at least a couple weeks to fill out the application and have a home visit, then you wait for an appropriate dog. Good luck!
