I was at the vet today with my new baby. Although mine is still a puppy I too am having a hard time getting her to eat. Or so I thought. The vet said at her size (1 lb 11 oz) a few kibbles every couple of hours is sufficient as long as she's not lethargic and drinks enough. I keep expecting her to eat a bowl full I guess
I also have her on High-Cal until she reaches 4 pounds. I've got a finiky eater on my hands but I've found that she tolerates Eukanuba bites even though it's not the higest rated grade of food
