Well we wormed our 2 week old pups with panacur yesterday and one puppy was very sick a couple of times and very flat. After an emergency vets visit fluids and an anti sickness injection we eventually got her to feed off mum some hours later. She seems a little brighter and is at least feeding now. My question is worming. The vet has suggested not worming any pups until they are 4 weeks and to worm with drontal. ( we obviously can't give that one puppy panacur again. Any opinions?

Hi Snoopy2007,

No expert here on worming but I do 2, 5 and 7 weeks with my pups. On Panacur which I have to do over three days each time (not had any problems) but know a lot of people who use drontal with no issues so you should be fine going on to that I think. I think drontal is just a one dose thing but not sure on that as I haven't used it. Hope your little pup continues to pick up.

Thank you

2 weeks is very early to worm. I wouldn't worm before 3 weeks. If you've wormed mum during pregnancy you should be fine to wait till they are 3 weeks. If you think about it, they haven't eaten anything except for mum's milk at 2 weeks. So for their first thing to eat in their lives then to be chemical worming medication with preservatives and stuff added, it's no wonder if it makes a puppy throw up or feel poorly.

I wean them and a couple of days after starting sloppy food, I worm.

I wouldn't assume you can't give that puppy Panacur again but if you do use something else, be sure it is Drontal Puppy and not regular Drontal (which shouldn't be given to puppies).

Ok thanks. It does make sense.

We always wormed our puppies from 2 weeks, and every 2 weeks up to the time they went to their new homes.    And never had any reaction - in fact after the first singleton puppy, we never saw any worms!!    However, we used Sherleys Worming Syrup.   Not Panacur or any other wormer.

Again after the first one, when we didn't, we always wormed our bitches before being mated.   They were wormed again 2 weeks into the arrival of the puppies, using Panacur usually.   But just the once.

After dreadful reactions in a litter, and so had a friend, ( we both had wormed Mum for last 25 days of pregnancy) I stopped the early dose, and now do 4 and 7 weeks.

Prior to buying in labelled bottles that is how my vet prescribed it and had no problems with that regime.

Yes that what the vet advised. Thank you

I think if you've wormed mum in pregnancy there's no rush to worm early.

Years ago already I heard too many stories about pups being ill and/or dying after being wormed with Panacur, so I have avoided it ever since. But to be fair if you ask around you will find just as many people who have had problems with other brands. Personally I use Drontal Puppy at 3, 5 and 7 weeks -or for toydogs 3, 5, 7, 9 and 11. (As they stay longer.)

I think if you've wormed mum in pregnancy there's no rush to worm early.

That's something I never do. Worm at start of season or time of mating, then nothing until the pups are done at 3 weeks, then the bitch is wormed as well.

She was due to be wormed during pregnancy but I didn't want to worm her then. We will worm her when we worm the puppies.

Thank you vet suggested drontal puppy but at 4 weeks. I haven't looked at what drontal puppy suggests for dosage but vet has advised not to do them until 4 weeks?

Because I worm Mum in pregnancy and first days after whelping, this reduces transference of worm larva via placenta and milk by 98%.

As a result waiting until 3 weeks to start first 3 day worming course seems reasonable. I have started pups on weaning foods by then so dose after meals.

I then dose next at 7 weeks, as this gives tums chance to settle before homing, if affected somewhat by worming.

I then advice owners worm at 11 weeks, so that hopefully they are not done at same time as vaccinations, so as to reduce stress on immature immune and bodily systems. Then monthlybto 6 months, revertingbto adult protocols thereafter.

I have found this system most effective for reducing issues duringbrearing and homing.

I do wonder if worming pups whose Mums were wormed too early causes isdues due to little or no worms???

I have wormed 8 generations of bitches in pregnancy and have never encountered any visible roundworms.

Unlike a friend who rescued a 6 week old wormy pot bellied flea ridden GSD litter.

On first day of worming pups were producing live worms both ends.

On second day two pups were very poorly, and vet advised not to give third dose, as large worm burden dying was releasing toxins.

They were wormed again 2 weeks later, producing a small number of dead adult worms.

They were not homed until 10 weeks once properly thriving.

Many attended the training class she ran with their new owners.

Most turned into lovely dogs, but most had delicate tummies.

Poorly bred, the ones I knew had .mobility/hip issues by middle age.

Drontal puppy only covers roundworm, but has advantage of one dose, but has to be repeated every 2 weeks.

Panacur is effective on more endo parasites, and monthly treatment is normally effective, but it's dosing over 3 days for pups.

For me using Panacur makes more sense as I need to dose Mum and the rest of the dogs with it.

I prefer to use Panacur because it is also effective against giardia, which can cause runny poops and be a problem for pups/mum.

WORMING:
Panicur is the only worming treatment I will use for my Puppies & Adult Dogs. Never had a problem. 
The Paste is great for Puppies and Liquid for Adults mixed with their food (always breakfast). 
Puppies have their worming at 3, 5 and 8 wks.
Expectant Mums are wormed from day 35 and the difference in Puppie's weight & coat condition in the first week and onwards is noticably better since adopting this method.
A great product IMO.  I Purchase in large bottle quantity by Vet prescription reducing the cost dramatically which means I always have some on hand
At this time last year it was in very short supply. 
Must be a top selling product. Can't see how it could cause longterm problems soley,  Perhaps there have been other factors involved in relation to the Litter highlighted?
