Nearly off mum??

At
2½ weeks? That's ridiculously early, and terribly bad for the pups. :( With my medium-sized breed (25kg adults) I wouldn't even
start weaning till three weeks for anything other than a large litter (10+ puppies), when I'd start a coule of days earlier. And I'd give them just a teaspoon of scraped beef each
a day for several days before progressing to a teaspoon twice a day. By
5 weeks they'd be on 5 meals a day, but would still be feeding off mum as well. Mum should be allowed to free access to and from her litter at all times.
These poor pups are being treated very badly, and the mother must be suffering greatly; eclampsia will be the next thing for her. The future owners of the pups are in for an expensive time, because these won't make healthy adults, being raised so appallingly.
