Hi Ladies,

3 week old pups that had their last day of 3 days of panacur on Tuesday are passing worms (dead) today (Friday). Does this sound to be expected 3 days after worming?

I'm surprised really as the bitch was wormed with Panacur throughout the last 3 weeks of preganacy and also again when pups were wormed.

Just wanted to know if 3 days after worming sounds reasonable for seeing the worms being expelled? Worrying I have a heavy burden but pups look fine ,plump but not pot bellied and gaining quickly. My sensible head tells me the worms will take a while to die and be expelled but my 'puppy head ' is worrying.

Thankyou all

I have never ever seen worms in 20+ years of using Panacur on 8 generations of bitches and pups.

What is the bitches worming history and did she pass worms?

I'd be worming the bitch at full adult dose if you haven't already and worm pups again within three weeks (length of time to adult worms).  Panacur should kill the adult as well as the larval stages.

I'd check the use by date on the packaging and check your dosage, and possibly contact the supplier/maker.

A rescue litter of GSD's who were incredibly wormy at 6 weeks, so much that one or two were very anaemic and they had only two days worming due to the amount being expelled both ends.

They didn't have any worms at the next worming before leaving the rescuer at 9 weeks.

This isn't my experience at all.  Like you my bitches always have Panacur during pregnancy (having used Drontal prior to mating.)

My pups are dosed for 3 days at 2 weeks old (Mum having adult dose for 1 day.)  I've never, ever seen a worm so agree with Barbara.  It seems so unfair when you've followed all the right procedures.  Glad they're dead though.

Thanks Brainless.

The bitch has been wormed with Milbemax before mating and wormed with the right dosage of Panacur in pregnancy. ( 6ml per day from day 40 for a 24 kg dog). Label well within expiry date...I always check that...supplier either my vets or Canine Hyperdrug. The bitch has been wormed with pups at 2 weeks of age at full adult dosage. I plan to worm them all again as I usually do at 5 weeks.

The worm passed by the pups are dead (only seen one roundworm so far) so I am hoping Panacur done it's job now...I'm just surprised to see them after using the Panacur regime. I've used it on 11 other pregnancies and never had wormy pups. The pups are all looking well,plump and growing like weeds so hoping this worming will knock them out.

She was five days early whelping ...I do wonder if missing some days of worming during pregnancy contributed?

Thanks Jean...yes does feel unfair but as you say they are dead so hopefully I can get on top of them now before the eggs hatch at next worming.

I was two days over the 2 weeks of age though due to me having to be away for a medical procedure and even though I left someone I trusted very much to puppy sit I wanted to wait and worm the puppies myself so I could weigh them accurately....not sure if the two days late would make a difference.

I saw a worm with my last litter after following the panacur in pregnancy too.
Just one and can't remember which worming it was. Also one the new owners saw a worm at 12 week (I think). I just took it as pup must have picked up worm eggs from environment and that worming was doing what it was supposed to do, get rid of them.

Interestingly I did have this bitch worm counted when she was three weeks pregnant...I do this periodically with all my dogs and this bitch was completely free of roundworms and has always been on other worm counts. I can only think that at some time she has had a roundworm burden not  that has created the cysts that have sat dormant and been re activated by the pregnancy

Thanks Noora.....that's interesting...it does say on the panacur data it reduces (not eliminates) prenatal infection...maybe it doesn't knock all the migrating larvae out.

> ....not sure if the two days late would make a difference.

Definitely not IMHO.  I think all of us, at some time or other has done it.  And I am absolutely sure that a bitch whelping early has no ill effects.  My girls only go 56 days as a rule and I have never considered it a problem.  I do Panacur for 2 days post whelp but I certainly don't worry that a bitch hasn't had enough doses.

So bucksmum don't worry! 

> this bitch was completely free of roundworms and has always been on other worm counts. I can only think that at some time she has had a roundworm burden not  that has created the cysts that have sat dormant and been re activated by the pregnancy

This is so as Roudworms don't affect adults that much a bit like demodex largely dealt with by the immune system.  it is PREGNANCY that activates the encysted larva as you say.

Maybe as I have generations of bitches whose mothers have been wormed in pregnancy, then been wormed correctly as puppies, that I have bitch with very little encysted larva to pass on, and so I never get to see the 'results' of the worming (dead adult worms).

All the hype about Toxocara and really the main infection comes from late pregnant/nursing bitches and puppies.  Adults when tested rarely have any.

I guess if the puppy has a significant worm load, you'll probably be seeing dead worms for a while.   Don't be tempted to redose until the set period has passed.   And before you do, I'd get a fecal test done, including for protozoa like Giardia, so you can be sure the puppy is clear.

My bitches were always wormed prior to being mated (using either Drontol or Panacur)  Not during pregnancy but again at around week 2 from whelping, at the time the puppies are given their first worming (using Shirleys worming syrup).   Only once have we had a puppy produce worms, and that was our first one, when I hadn't, to my shame, wormed the dam as I did after that!!

I'd send my puppy buyers home with a worming history, when done and with what, and a recommendation that they worm again at around 3 months, depending on what their vet advised too.

Hi again Ladies,

Having done a lot of digging and asking around it seems several other breeders have had a worm issue even after using Panacur very carefully during pregnancy and also had wormy pups even though wormed at 2 and 5 weeks and then had to resort to Drontal to clear them out. I must admit I have lost faith in the Panacur as I know I wormed her very carefully at the right dosage......there are some who believe there is some resistance to the panacur...I don't know but i'm not happy with the results this time.

Anyway,I'm thinking of using drontal at next worming. As the protocol for drontal is every two weeks do you think it's safe to use this 2 weeks after Panacur? As with Panacur you have to leave 3 weeks inbetween but as I have a worm burden I don't want to leave too long so they get established...can I use drontal 2 weeks after panacur safely? I would have though the panacur would be well out of the system by then.....

The above is what I ended up doing, giving drontal.
I can not remember how long I left in between though! Still had that one pup pass a worm at 12 weeks when with new owner...

Noora...thankyou...did you give up with panacur after first worming and move to drontal for second? So annoying when you have followed exact protocol for Panacur but not that uncommon it seems.
