[RottieGirl86]

My female puppy was 40 lbs at 4 months and now is approx. 60 lbs at 9 mos. She was a slow grower, which I liked. Someone told me my rott was underweight and how they could make her "fatten" up so she'd be full grwon by then ( 6 mos at the time, geez.)

I would not worry so much about the weight as in what the dog is eating now. Our mutt (Pek mix) was severly underweight, you could see ribs on her when we rescued her. It takes a good bit of time for the dog to settle and put on the weight, but the key is doing it slow, so their systems can adjust as they adjust to the new house as well ( IMHO.) Depends on the shock and how much they trust humans.

Lots of good food choices out there. And lots of posts here about them too. Sasha, my late rott, fluctuated between 75 lbs to 95 lbs ( people had to feed her table scraps, *eyeroll*, that stopped when Vet said she was overweight at 95 lbs. for her frame.)

I take it the Calcium was just short term use? Did the vet do a blood work up? I wouldn't worry then.

Congrats on your puppy!
