Sorry everyone I have had issues logging on which Ben just corrected. I am still interested in a safety cover but I am only trying to protect a 15 pound dog not an elephant He stays clear of it with no cover but I am just concerned that he might interpret a solar cover as a solid surface. I did buy a 15' round 16 mil solar cover with the intent of trimming it to fit. I stopped when it dawned on me I could be putting our pooch in danger.
