My first hound I took a week off, she came right from a group but was never in a foster home, and she adjusted very well in a week. When I went back to work, I would come home at lunch to put her out to potty, but I soon stopped that because she would look at me like, why are you waking me up My 2nd and 3rd hounds had lived in homes before so they were fine with Friday, Saturday and Sunday to get into the routine. Greyhounds are use to a routine , so I would suggest to get on a routine that works for everyone and try to stick to it. Congratulations on your new hound
