Ok my puppy doesnt eat as much as it says on the bag, she looks good, but isnt eating nearly the amount it says!!!
Should i see a vet?

If pup looks good and is eating as normal, drinking as normal, playing as normal and her motions look nice and firm I would think shes ok- just like humans not all dogs will require the same  amounts of food. But theres no harm in getting pup checked over if it puts your mind at reast :)
