Hannah is a little over 6 months and stands at about 18 and a 1/2 inches tall. She's probably right around 30-35 pounds. I was wondering if maybe she is a midget. Her siblings from her litter are a lot bigger than her. She just seems so fragile and dainty next to her gigantic brothers and sisters. Her one sister is almost 21 inches tall and she's almost 50 pounds! I thought I was feeding her correct (she eats 4 and a 1/2 cups of kibble per day and probably half a can of canned food). Am I starving her and that is why she is not at the size her siblings are? Her siblings (who were kept by the breeder 2 females and 1 male) are fed free choice and have food available to them at all times. Is that why they are growing faster than her? Should I be worried she is so much smaller than the others? Will she catch up with them in size and weight?
