My 2-week-old puppy is weak and slow after deworming. Is this normal?

Updated On September 23rd, 2025

Pet's info: Dog | Shih Tzu | Female | 12 days old

Can someone please help me. My 2 weeks old puppy moves like a turtle and I think she is pretty much weak compared to before. It might have happened because of her deworming just this afternoon. I have no vet clinic available right now because of ECQ curfew but will open tomorrow morning. Is it normal? If not, what should I possibly do until tomorrow morning? Any help would be appreciated P.S. She weighs less than half a kilo I think and she can still crawl if I move her

I can’t think of a way that this would be related to the most common broad spectrum dewormers that we use but it would help to know what kind exactly. She may have low blood sugar or an infection. It sounds like she was moving better before today, but if not some puppies have abnormal leg muscle formation and it might be something like this (swimmer puppy). If she hasn’t been eating well, if you’ve seen vomiting or if she seems disoriented you should rub some honey on her gums and see if you can find an emergency vet somewhere. Otherwise head to a vet in the morning.
