Zeus refusing walks all of a sudden

I’m looking for advice on how to get my 7month old GD to actually go for a walk… recently, we get to the end of the drive way and he just pulls to go back, every time. I’ve sat with him in the drive way for a good while, given him treats when he goes further … and that doesn’t seem to be working, anyone with access to my ring door bell would be in a fit of laughs! Any tips as I’m keen to have him socialised as much as possible but he’s just not having it🙄 pic of velociraptor Zeus for reference
