Different breeds develop teeth in different ages, i had Yorkies forever and we are used to see teeth coming in as earlier as 4 weeks.... then i got shihtzus.... at 12 weeks they had almost no teeth, and so baby like and not like Yorkie at all....
So i would be careful on jumping on early conclusions about your puppy and at 7 weeks it is just a baby anyways, '
I also believe that the recommendation is to hold the puppies with the mom until at least 8 weeks old no matter what breed it is. I often hold my tiny ones for 12 + weeks and only send them home if i am sure they will be ok.
So it varies a lot....
I hope it helped you, but if you are happy with your puppy... and she eats sleeps ... it is very normal for a baby to take many many naps a day ... even at 10 ---12--- 16 weeks old, and they need it in order to be happy and grow it also avoids hypoglicemia.
Good luck.
