Thanks Frenchy.....the mom already had trouble getting her bowels on track, so i don't think i'll try the Satin balls before speaking to a vet this week.
Still trying to figure out a way to put weight on her. She only has 3 pups, but their combine weight, is almost has much as their mom's total weight and they're only 4 weeks old today!! The pups are being fed 4 meals a day to help the mom out...so she's only nursing them about 4 times a day....gradually weaning. But still not putting on any weight and still too thin! Guess i'll wait and see what the vet says this week.
Thanks again for your help!
