Lawn sprays and Pyrenees-- This year we are going to have a commercial company come in and spray the lawn. Do the chemicals afflict Prys? What do I need to look for? I don't want Emmett getting sick if I spray. I heard it can burn the pads on their feet. I don't have booties, and I think he would just take them off anyway. What can I do. The lawn is in need of the treatments. Mer :o)
