That's too bad,
max was like that, he would roll to get what he wanted, so heactually didn't "crawl" till about 10 months, but he walked soon after.
Really it was our dog pugsly, W ho motivated him by being awesome. He walked just out of his reach and max had this look "!!!!!!!!!!DOGGGYFRIEND!!!!!!!"
I gave max a little taste of slurpee, he did but like it, by the face you would have thought I gave him a pickle.
