16 weeks & 28 lb Male - Concerned?
I have a 16 week old male GSD, and he was weighed last Friday and he is 28.6 lbs. I am a bit concerned considering that he seems small for his age and sex, and the fact that he is 14 lbs less than what my female GSD was at his age. At first he was growing at a normal rate, but then seemed to stop growing as quickly at around the 3 month mark. The vet didn't seem too concerned, but he did ask how often he was eating in a day.
His parents are both 80 lbs & 100 lbs, so him being this small at this age worries me. He was not the runt, and was actually the second largest in his litter.
I am currently feeding him Victor at 2 1/2 cups a day, with extra supplemental foods (pumpkin puree, salmon oil, rice, small amounts of raw meat/eggs). I am now wondering if I made the mistake of not giving him puppy food as I did with my female (she was switched out at 4 1/2 months to Victor), so I am going to switch him to Fromm's large breed puppy food (but I'm wondering also if I am 'too late' now by doing this).
He recently overcame a case of Giardia, so I am wondering if that played a part in it.
What do you guys think? Should I be worried?
