Puppy weak, wobbly after horse dewormer for worms. What should I do?

Thank you for submitting your question regarding Maze. I recommend that she sees her veterinarian right away. This is a dramatic response to a dose of deworming medication. If she had a very large parasite load, the dewormer could make her ill as the worms die off. However, most puppies are not as sick as you have described. She could also have another disease that presented at the same time. Regardless, she needs veterinary care. I worry that her blood sugar has dropped low as she is not eating well. This can make a puppy weak and wobbly. I hoep this information helps and you get her feeling better soon.

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.

Poor pups. While a heavy parasite load can cause severe GI upset, and anemia which can cause a pup to become extremely lethargic, have bloody diarrhea, etc, I would also want to rule out underlying illnesses as a possibility. It would be best to bring them to a vet ASAP especially if they are lethargic or unable to keep any food or water down as puppies can quickly become very dehydrated. They may also need supportive care such as an IV or injected medications if they are very ill from the parasites or other causes. You can try continuing to offer water, or rubbing a little honey on their gums for energy until you can get to the vet, however due to the severity of symptoms it would be best to seek emergency care.

Hi, I'm worried if Zoey is still weak and vomiting. Young pups don't have much in reserve so if they stop eating they can deteriorate very quickly. It could be related to the de worming medicine if she had a lot of worms that died quickly, or she may have an illness like parvo, giardia or coccdia. If she's not eaten today, take her to the emergency vet tonight. If she's eaten some and is still walking about, take her in the morning.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! In the US we do not use Albendazole in dogs or cats. If Oscar only weighs 5.5 lbs and if he was given 5mls that is 200mg of albendazole and at that dose it has been reported to cause mental dullness and decreased appetite in cats. It can also affect white and red blood cells. I don't have much information about overdoses in dogs. Stop giving him the medication. The dose of ivermectin should be ok. If he gets worse or doesn't improve he should be taken to an emergency hospital. Good luck!

Hi,t hanks for using Petco Pet Education Center, formerly Petcoach! Dewowmers have the potential to cause an upset stomach such as vomit, diarrhea and decreased appetite. Though I am worried something else is going on since you lost a puppy recently. I worry most about parvo virus in puppies this age, especially if they are yet to be vaccinated. I would have this puppy seen today by your Vet and tested for parvo virus as it is VERY contagious and if it is the cause it will likely affect the entire litter. If it isn't parvo the Vet can at least get this puppy feeling better and prevent dehydration. Good luck!

This looks like roundworms. You need to deworm this puppy immediately with pyrantel pamoate and febantel. They can be dewormed with this product as young as 2 weeks of age. I suggest you give a dose now and then again every 3 week until the puppy is at least 4 months old.
