Found German Shepard on porch (San Antonio)

Male German Shepard with light brown eyes showed up at my front door last night.
My puppy is in heat and he hasn’t left my yard unless it’s to follow me and my puppy on our walks .
He seems like a great dog, looks well groomed and taken care of.
If this is your dog or if you may know who he belongs to please have them contact me for location to get him back to home.
