Geen borstvoeding, keizersnedes en dan 'seeding'...
Beter hondenmelk geven dan, krijgen ze ook immuniteit van.

“Passive” Is Aggressive Protection
Most mammals (animals that drink their mother’s milk as babies) are born with incomplete immune systems. They are not capable of developing their own immunity and they would almost certainly die unless they got immunity from an external source. So they rely on “passive immunity” to survive. Passive immunity simply means immunity derived from another individual.
Human babies acquire passive immunity while still in the womb. The maternal antibodies cross the placenta to the infant, and the baby is born with some protection from disease.
Dogs have a different method of granting passive immunity to their offspring. Puppies (like calves, piglets, foals, and kittens) receive little or no maternal antibodies while in the womb – little or no maternal antibodies cross the placenta to the puppies, and the puppies are born with very little or no immunity to disease. They rely on drinking their mother’s colostrum after they are born to gain the antibodies they need to survive.
Colostrum - it’s a two part story
Just to review, colostrum is the first milk the bitch produces in the first few hours after whelping. One of colostrum’s principal functions is to pass on maternal antibodies to the puppies. Whatever the bitch has immunity to, her puppies will also have immunity to, if they drink her colostrum in a timely fashion. There’s a big catch, however, which this clip from our film “Puppy Culture” explains.
