I remember (watching the show in reruns as a kid) the robot as the B-9 Environmental Control Robot. On his packaging (a box or a metal cabinet, I think) you can see the name G.U.N.T.E.R., which is an acronym for General Utility Non-Theorizing Environmental Robot.
It should be your mantra whenever you apply products to the lawn. This doesn't have to be a lengthy ban. The Dog Owner's Guide suggests keeping pets off treated grass for 24 hours, as nitrogen can burn the pads of a dog's foot.

Finding Lost Pet. If your pet is missing start checking with various animal control centers in your area. If your pet is brought to an animal control center as a stray/found animal, they only have to hold your pet 3-5 days before they put your pet up for adoption and after the 3-5 days your pet can be put to sleep. It is very important you go to the animal control centers in person; do not just call or fax over a picture!
