Home Improvement

I'm moving into a house with a pool in a couple of months. I have a 20# dog who is blind and I'm trying to think of ways to keep her safe. The area from the back door/patio to the pool is all concrete, so installing fencing would require drilling holes. Looking for something temporary that could be removed during parties. I suggested wooden planters spaced every 8+10 feet with a bracket to hold a board. Husband didn't like that. I'm still leaning towards that, but looking for other ideas. Thoughts?
