a) Saks brings approximately her own body weight in dirt into the pool every day.
b) She takes away just enough to have muddy paws which she then dries on the nearest bystander (usually me).
Hmmm... I'll have to see what I can do about those problems. I think the current plan is going to empty it out on a weekly or bi-weekly basis. This will help water the lawn and it'll return the dirt/mud to it's proper place in the lawn. I'm not sure about what to do about muddy puppy prints on clothes though. Saks is having trouble learning not to stand on people. This is not a big problem right now, but as she doubles and quadruples in size this could actually maim people in the future ;)
