Sadie is also 5 months and I can't imagine her ever being finicky about food! She always seems to be on the prowl for some grub, passing by her bowl and giving it a rattle many times a day. When it is feeding time, she vacuums it down so fast I worry she'll make herself sick. She gets 1 cup, 3x per day. The vet suggested I don't increase. She is getting enough, just displaying the lab side of the family in terms of appetite.
