Our little Prince Francis is 5 1/2 months old now and growing like a weed! He seems to be getting longer, although not much taller, ha! Last time he was weighed at the vet he was just under 15 lbs. That was when he was 17 weeks old. I weighed him yesterday and he is now 18 pounds. I've read that corgis go through a major growth spurt between 5 and 6 months, so I am just wondering when he will start gaining more weight. I figured he would be gaining more weight more rapidly at this point, but he's not. He's very happy, I feed him twice a day, and he eats almost everything I put down for him. I feed him a little over a full cup of Iams proactive puppy food. He gets a few fresh green beans with each meal and a few in between for treats. Sometimes he finishes his food, sometimes he leaves a little. Everything else is normal. i.e, exersize, sleeping, and almost all of his big boy teeth have come in. Should I be concerned that he's not heavier, or am I being an over-protective mother?!?
