I dont know where you live but Nichols Vet in Wayne is very reasonable on pricing. I think you need to take the puppy to the vet or you may lose the whole litter. I just had 2 cats neutered at that Vet for 120.00 for both. If you cant afford the care for the puppies maybe you shouldnt breed them till you can. Sorry! Also, If all the other pups are 3 pounds and this one is only 1/2 pound that right there tells you something is wrong with this puppy, runt or not.
