This is yet another reminder that dogs are not permitted on school grounds. Please remind other adults who may accompany your children (babysitters, grandparents, etc.) that they may not bring their dogs onto school property while dropping off or picking up your children.
There are children and adults with allergies or fears of dogs. We also do not want to have to deal with dog mess. In addition to this, it is very unfair on the animals to be subjected to excited children who may want to pet them.
However friendly your dog may be, and whatever the size of animal, please abide by these regulations which are designed to keep everyone safe.
