Our "A" litter (mom and pups came into rescue when they were 1 day old) is now 24 days old - they are becoming quite mobile and one has already bailed over the welping box wall (much to her loudly voiced dismay) they also have teeth starting ... ouch

Moma dog is not too impressed.
About what age should we introduce supplement food and does anyone have a good formula or recipe?
Thanks
