> Interesting you say to worm just twice, I have never heard of that.
Hi there. It is me and a few others who have had experience of problems worming so often with Panacur after already worming the Mum.
My now 13 year old eldest and some of her littermates were very poorly, and a friends puppy ended up in vets on a drip.
Going back historically.
with my first two litters the Vet dispensed me the Panacur with instructions to worm at 3 and 7 weeks, as well as doing Mum during pregnancy. did this with no problems and gave the pups and me time to ensure no reactions before them going to new homes.
The next litter I bred I got the wormer in a 100ml bottle packaged by the manufacturer with their instructions to worm at 2-3 weeks, 5 weeks and 8 weeks (3 day course each time), this is the litter I had problems with, as did a fellow breeders some weeks earlier.
The next litter after that and every litter since I have wormed at 21-23days, and 7wks - 7wks 2 days. I have never seen worms from any of my pups and have now been worming 6 generations of pregnant bitches and their pups.
What I do find is that their appetites can fall off a bit during the worming course, usually a bit on the second day and a bit more the third day, and some become a bit fussy as if they perhaps have indigestion, and toothpaste consistency stools often result, but they soon are back to normal.
They then leave with instructions to worm again at 11 weeks (so as you say it comes between vaccinations), and monthly to 6 months with the three day puppy dose, and then as adults.
Also re vaccinations, I do not let a part vaccinated puppy go to it's new home as if the vaccines used by new owners vets is a different make they will start the course all over again, with puppy ending up being over vaccinated at a stressful time in their lives.
Pups going before 10 weeks of age of without vaccinations, puppies destined to go after 10 weeks will have both.
