Why do all puppies have worms when they are born and have t wormed?

Just curious...I mean if the puppy has just been born how do they have worms ...cause you always see in ads that the puppies have been wormed and have shots....Just one of those questions to make you say hmmm

they get it from their mother..from the milk..

They aren't BORN with worms, but they do contract them easily. Puppies have little immunity and can catch just about anything they come in contact with. Worms are just one of those things that's everywhere poop is, so you have to deal with it. It's probably one of the most common "ailments" that dogs come in contact with, even older dogs. It is common practice to worm and vaccinate all puppies, regardless of if they have worms or not. So, just because they were dewormed didn't necessarily mean they HAD worms, only that the owner took that precaution.

Hello, The below information is what I send home with every puppy that leaves us, I put it together after researching that very question! Enjoy! Sorry it is in all Caps.IMPORTANT INFORMATION ON INTERNAL PARASITES otherwise known as ‘worms’INTERNAL PARASITES BETTER KNOWN AS ‘WORMS’, CAN BE VERY SERIOUS IF NOT TAKEN SERIOUS BY YOU AND YOUR VETERINARIAN. IF LEFT UNTREATED, THESE PARASITES CAN EVEN TAKE THE LIFE OF YOUR PUPPY. SO PLEASE CONTINUE TO READ TO UNDERSTAND WHY AND HOW TO TREAT YOUR PUPPY.THESE PARASITES HAVE ‘LIFE STAGES’, WHICH BASICALLY CONSIST OF EGG, LARVAE, & ADULT. ONCE THE EGG HATCH AND DEVELOP INTO LARVAE THEY MIGRATE INTO THE TISSUES OF THE BODY. WHEN A PUPPY IS EXPOSED AND HAS BEEN GIVEN THESE PARASITES THEY CAN MIGRATE WITHIN THE SKIN, MUSCLE, AND LUNG TISSUE’S, BEFORE DEVELOPING INTO THE ADULT STAGE IN THE INTESTINAL SYSTEM. A SMALL PORTION OF THE MIGRATING LARVA WILL BECOME ENCYSTED (ENCLOSED IN A SAC OR CYST) WITHIN THE MUSCLE, AND LIE DORMANT, ESSENTIALLY ‘LAYING IN WAIT’ FOR MONTHS EVEN YEARS BEFORE RESUMING DEVELOPMENT. THIS PUPPY IS DEWORMED THROUGH OUT PUPPYHOOD AND EVEN PUT ON PREVENTION. SO WHY DOES THIS PUPPY THEN GROW UP AND EXPOSE ‘HER’ YOUNG TO THE PARASITE? DURING PREGNANCY AND WHELPING, THE ENCYSTED LARVAE IN THE DAM (MOTHER DOG) ARE STIMULATED BY HORMONES TO CONTINUE TO DEVELOP FROM THEIR EXISTING STATE. THIS STAGE OF THE PARASITE AS WELL AS THE EGGS OF THE PARASITE CAN PASS THROUGH THE MAMMARY GLANDS TO INFEST THE INFANT PUPS WHEN NURSING. IN SOME CASES PUPPIES ARE BORN WITH THEM AS THE PARASITE CAN ALSO PASS THROUGH THE PLACENTA AND INFEST THE UNBORN PUPPY. SO THE CYCLE IS A CYCLE THAT CAN BE KEPT UNDER CONTROL, WHEN YOU TAKE YOUR PUPPY TO THE VET AND HAVE THEM TO DO A FECAL EXAM TO CHECK FOR PARASITES. IF THE TEST IS POSITIVE, HAVE THEM DEWORM THE PUPPY. WHILE AT THE VET HAVE THEM PRESCRIBE HEART WORM PREVENTATIVE WITH EXTRA PARASITE CONTROL (INTERCEPTOR, HEARTGARD PLUS, ETC) THIS WILL KEEP THE PUPPY FROM REINFESTING THEMSELVES.HERE AT OUR KENNEL, WE USE STRONGID-T ON OUR INFANT PUPPIES AND OUR ADULT FEMALES THAT ARE IN WHELP (PREGNANT) AS IT IS THE SAFEST DEWORMING PRODUCT ON THE MARKET AND IS WHAT YOUR VET USES. THIS DEWORMING MEDICATION RIDS THE PUPPIES OF ADULT ‘WORMS’, HOWEVER THE SAFE PUPPY DEWORMER DOES NOT RID THEM OF THE EGGS, OR LARVAE. THIS IS WHY YOU AND YOUR VETERINARIAN MUST KEEP THE CYCLE UNDER CONTROL BY CONTINUING TO DEWORM, AND DURING THEIR VERY FIRST VISIT TO YOUR VETERINARIAN TELL THEM YOU WANT YOUR PUPPY STARTED ON HEARTWORM PREVENTION NOW. THE HEARTWORM PREVENTION HAS AN ADDED INGREDIENT TO BREAK THE CYCLE AND CAN NOW BE STARTED AS YOUNG AS 8 WKS OLD.
