Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Pingo is very adorable!
At 6 weeks of age, Pingo is still very young. It is normal to play for short periods and sleep a lot. Just like a human baby. Also Pingo is a small breed dog and her stomach is small. I would be sure to feed her small amount every 6-8 hours until she is 12 weeks old. The volume will be small due to her size.
If you are still worried about how much she is eating then repost with the total daily volume she is eating in cups.
I hope this helps and I wish you and Pngo the best!
