You know, you don't have to walk every day. It's a complete myth (particularly propagated on MN, imo). 20 minutes of sniffing is equivalent to a 1hr walk. 10 minutes of brain games ditto.
You could do scatter feeding in the garden, put kibble in a cardboard box mountain, hide kibble around your lounge... They're all really valid things to do.
If you're struggling to get out of the front door...I wouldn't. You're just ingraining the fear and hatred. Go back to basics and do heel work without a lead in the garden, then add a lead, then work on getting out of the gate and going straight back inside (lots of treats) and build up.
If the dog isn't enjoying the walk, the walk isn't for the dog, and if you're not enjoying it, it's certainly not for you. If it's not enjoyable for either of you....why are you doing it? You'll need spend a couple of hours dealing with the fall out of the stress it causes you both.
This will pass but go easy on yourselves and have a think about why you're doing what you're doing - I bet it's because you think dogs 'should' go for a walk every day. At this age, the garden (assuming you have one) can be plenty to burn off any excess energy and they still have so much to learn.
