I am debating on drippers vs. micro sprays for a plant plot in the back yard of a "doggy" yard. Each has good and bad. I think either way I go, the dog will chew the stake, or dig up the tubing and destroy it. Any ideas that have worked is appreciated. Area covers small flower / non flowering plants (perennial) and other areas around perimeter of house w/ shrubs / roses. Besides removing teeth from dogs, have you got any suggestions that have worked for you?
