HI Kim..Suri is a doll baby! I'm going thru the very same situation as you...with my Tulip. I did the growth chart deal with her and according to it she should be around 3 lbs...however she's only gained 1 oz...in 12 weeks! I spoke to my vet and he says apparently this is normal for her... each dog is different..
I did the same thing with my other little girl, Daizy and the charts were right on...She stayed at 5 1/2 pounds since she was 5 months old now, however she did just gain 1/2 a pound and she's almost a year. So she's now 6 lbs!
I spoke to someone else and they had a very small little girl and she said her baby hardly grew at all but around a year she put on a lb or so...
I guess we'll just have to deal with our babies no matter how small they are or how big they get....lol I was hoping that Tulla would make it to 3 lbs...too! I have 2 large dogs...and it is scary with this tiny 1 lb. 8 oz. baby running around their feet. She hardly feels like a dog..she feels more like a kitten to me...lol she's so delicate!
so good luck to us both!
