doubleing the twelve week weight didnt work for me...... AT ALL...... toby was 3 lbs at 12 weeks...... so you would expect him to be around 6 lbs right??? WRONG... he was 8 lbs when we took him in to get neutered at 5 months, and he has had a little growth spurt since then so he might way 9 by now.... thats way off from the 6 lbs that was predicted... as for the ears, if you want them up, then shave the top and tape them... personally i like the ears floppy, i think he is sweet looking
