How far would you go to save a litter.

I have a litter of 11 babies that are 3 days old. The mother is a fox red Labrador and the father is a Silver Lab. They are all black and in all a very healthy litter. <br><br>One of the babies is runt and has not sucked. It is really weak and probably isn’t going to last the night. We have been supplementing it with formula through a bottle but so far it’s not looking good. <br><br>The mother is a great mother but the litter is so big I think she forgot it was there as it’s only 70 grams and the others are all 280 grams average and two are close to 300 grams. <br><br>We are going to get the runt to the vets tomorrow to see what the options are. <br><br>How far would you go to save a runt? <br><br>We will do absolutely everything in our power to save it.
