Ryder is 14 1/2 weeks old and hasn't gained anything for the last month or so...
He weighed 18 ounces around 8 weeks, and since then he's gained 2 ounces...so he's been 20 ounces for about 4 weeks now!
He's round and chubby, and he eats VERY well ALL the time, has never had a sugar drop. He's just getting over a cold and has recovered fully, still eating like a pig throughout the illness.
What could be wrong?
