Staffie puppy

Sareece • My name is Sareece me and my fiancé been together 2 years now we sadly had a miscarriage last year on 22/10/14.
I just got a 8week old full pedigree Staffie we have called him Bailey but finding it hard to get him to do his bisnas on a training mat as who we got him off just let them out side and he had no jabs yet I have him book in on 17th to get them so can't go out till then but he won't do the toilet in his training mat he'll walk off it and do it on my carpet eny tips on what to do don't want him out side till I know he will be safe after his jabs
