I have never seen webs like this and want to know what kind of spider this may be related to.

I am concerned as the location is home to 40 retired greyhounds at a dog rescue.

Thank you so much for your thoughtful and extremely helpful response! I have found at least ten of these webs at the rescue kennel; hanging between rafters. You are correct that there are lots of flying insects in the area; mostly flies, moths, and bees.
