My puppy missed dewormer. Is it safe to re-dose before vaccines?
Hi, I would not repeat the dewormer dose as you do not want to overdose her on the dewormer. She should be dewormed again in 3 weeks to make sure you got the life cycle of all the parasites she may have. If she is not having diarrhea or weight loss she may not even have worms. There is not a need to deworm her before the vaccines, they will still work properly regardless of the worming. I would go to your vet for vaccines and bring a stool sample with you to see if they could check it for worms. Depending on what eggs they see, they might recommend a different dewormed like pyrantel or panacur (fenbendazole). Either way, i would not redose her because she is so small and it is easy to overdose them and make them sick. If your vet suggests something different, you can follow his or her instructions. Good luck, i hope this helps!
