impossible to see and act on nine dogs that are pooping at the same time, can i also agree with ms. katz that pointed up the other problems you have when you have a large number of dogs, so i would suggest that the regulations recognize some of these issues and that the number be limited a little more. supervisor wiener: they keep. ms. stevens? >> hi, sally stevens, sf dog. the route the years, we have stress six or seven dogs per dog walker. when dogs are not under control or when pooper is not picked up, it reflects badly on all of us, whether you are a dog walker or a dog owner. less than six i do not think it's economically feasible at all, because the price will go up, and it will price people out of being able to afford dog walkers, so any more than that i do not think will work, between six or seven is good. seven is a nice compromise. we can accept age, because it is better that the process goes through, because right now we have in affinity. six or seven, seven may seem like a nice compromise, and we could lip -- live with aids, but the important thing is to get this process goi
