I've never had to worm a litter yet, knock on wood.

Donna, I know you haven't either, since your dogs are on heartworm.....automatic dewormer......When I lived in Texas, I would take my girls off of heartworm, just prior to breeding, 2 weeks after the litter was whelped, I'd put mom back on heartworm meds.....

To the original poster.......your best bet would be to take a collective poop sample in and have it checked (if one pup has worms they all do, including mom). So, they'll have to be treated. However, Nemex II is a mild dewormer that works wonders, if worming is necessary. But, keep in mind Nemex II does not kill tapeworm, your vet will have to prescribe tapeworm meds for that.....and then you can't administer until a bit older.
