My sisters puppy Mercedes also went potty on their patio the first few days they had her, it was solved by only taking her outside to potty on a leash, after she ate/drank/played/slept. They led her over to the grass in one corner and let her potty there, now she only potties in that corner, which is also easier to clean up! it's pretty simple!

I wouldn't be leaving Gracie outside for too long alone, anyway. . puppies can get into a lot of trouble unsupervised
