Not only don't I think a mom could pass more along , a puppy couldn't absorb/utilize them even if she did. This article say 18 hours...definitely not after the 2nd day, so again, additional protection does not vary with when a puppy is weaned: Newborn puppies, through some process that we do not fully understand, are able to absorb the large maternal antibodies into their blood system through their intestinal wall unchanged. The absorption of these large protein molecules is one of the peculiarities of newborns. As the puppy ages, his digestive system begins to hydrolyze protein molecules. This is a process in which a molecule of water is added to proteins, breaking them into smaller sections. This is important because if the maternal antibodies are hydrolyzed, they lose their ability to destroy disease causing viruses and bacteria. Usually, toward the end of the puppy's first 18 hours of life (may be as few as 12 hours) he loses the ability to absorb these antibodies and they are hydrolyzed. Therefore, even if the mother continued to produce colostral antibodies, they would be destroyed and not provide any protection to the puppy. It is important that we now clarify one often-misunderstood point. As stated, colostrum with its antibody protection is only present in the first 24 hours of milk flow and newborns can only gain colostral immunity if they nurse during that time frame, and they are less than one day old. After that, it makes no difference how much or how little they nurse; they will not absorb any more antibodies. Many breeders and pet owners believe that as long as the puppy is nursing, she is gaining more antibody- protection. That is unfortunately untrue. Others feel that by allowing older puppies to nurse on a new mother, immediately after she gives birth,it will give the young animals another dose of maternal antibodies. This is also untrue. Remember, newborns lose the ability to absorb antibodies at approximately 18 hours post-partum.

Puppies are only capable of absorbing antibodies from their mom's colostrum for the first 24-48 hours. It's a question of when that protection wears out.... So you don't think that there is antibodies passed along in their daily milk, but just from the colostrum? I thought antibodies from disease passed into the regular breast milk just like allergy resistance and hormones naturally; plus drugs and the like that get put into mama dog. So, the maternal antibodies wouldn't start to run out until the pups were fully weaned. I'm extra grateful to know my pups are generally nursing 5 minutes after they're born. :). Just enough time to dry them up ribbon & weigh them. I'm also from the school that putting the pups to nurse helps stimulate labor by the nursing stimulating the natural production of oxytocin.
