I didn't do it anything, I like him floppy or standing!
hehe. They eventually did stand though by themselves (well... not totally, he went to the groomer and she shaved the tips) and that was at about 4 months of age. They've been standing ever since.
First pic - 4 months old, after first grooming, this is what they did for a few days...
Second pic -they're like this all the time now at 7mo. hehe
Third pic - Him at 9 weeks old, aww, those floppy ears
