i wormed my litter of pups at 2 weeks as advised by my vet and am aware that it should be done again at 5 weeks and 8 weeks, BUT i have made a mistake i have only done it once and on re reading the instructions it should have been done 3 days in a row. I only gave one day, should i give them some more now or leave them now until they are 5 weeks????

Ask your vet!

How much time has past since you gave the first dose and how old are the pups? you may have to start the course again. Call your vets and ask about the dosage...they will be able to help! Liz x
