well that precious baby is eating well lol
my bentley was a CHUB when he was a wee thing...i think at 6 or 7 weeks he was over 1.5 lbs...he was so chubby he had baby fat rolls all over his body, especially on his little arms and legs...there were only 2 in his litter so he ate well ... and also, he had a TON of hair and that made him look even bigger LOL...i seriously thought he was going to get to about 6-7 lbs which was okay with me
well fast forward to almost 5 months old and he is 2.5 lbs and gaining slowly...he is growing into all his skin finally and looks perfect for his size...
so no, i do not necessarily think he will end up being a chub
