Such a cutie - hope you find her and him great homes. Judging from her photos, though, it looks like she has worms (most puppies do).

Have you had a chance to get them in to the vet yet? If not, there is a great wormer you can get at feed stores called Safegard. It is technically a goat wormer, but it has the exact active ingredients as dog wormers (fenbendazol 10%). It is very inexpensive at Tractor Supply and the dosage is 1ml per 5lbs each day for 3 days, then repeat in a month. Fenbendazol kills all 4 types of worms. We usually worm all our rescues at intake, because sometimes it take a few days to get them in to the vet. The rescue vets are great, but they usually only have time to do basic vaccinations and a quick health check before they send them to us.

Worming is so important in puppies since worms can really do some major harm in small pups, but I'm sure your vet has already told you that.
