Archie doesen't sit properly

Every time he sits down his "lip stick" comes out and he can't sit properly.
What could this be? I can't train him to "Lye down" because of the way he sits..

Thank you.

true, I can't teach him to lye down though he rolls over on his back maybe because his "lip stick" is popping out ?

How old is he? Maybe he'll grow out of it

Around 9-10 months now, born 8 weeks before 1st of May

Still quite young then

Bacchus sits at the kerb before crossing the road but in this colder weather he doesn't quite "touch down". Can't say I blame him.   

He's "full of the joys" at the moment Ashley, like a teenager! Chances are he'll grow out of it.

It's perfectly normal! Dogs of all ages sit like that. It won't stop him lying down - if he lays down, he'll put it away!
