Hope you have some good news to share with us.
If only sad news, I don't need to read it and agree with Margot49. We have a 24/7 animal hospital less than 10 miles from home, in such a situation that's where my struggling mother and puppies would be in a situation you describe.
No answer please, but hope you are not running a "low cost puppy mill".. and hope that the mother has a good loving contact with humans when just being a dog out for a romp.
Wishing a Happy New Year to all, including all pets.
I will hold my tongue on this.
Do you see any part of the puppy in the vaginal area when she pushes? Any discharge, like a green color?
The puppy could be too large, be breech, turned, two pups at the bottom of the horns at the same time....... Christmas or not, I woukd probabky be contacting your Vet or the ER clinic.
Why are you breeding this dog? You should be more educated then you seem to be.
Good luck. Hope all turns out well for your dog.
Please come back and update.
