Why is my dog wobbly and dizzy after taking a deworming pill?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I have seen deworming pills cause an upset tummy: vomit, diarrhea, decreased appetite. It usually resolves in 1-2 days. The pill may not be the cause of why Lucy isn't acting normal. If it has been 2 days since you gave the pill I would have Lucy seen by your Vet to make sure she is ok. I hope this helps and I wish Lucy the best!

Potentially. It depends though on what the other medication is. Dewormers can upset the stomach or cause diarrhea which may decrease the absorption of other medications. It may be best to ask your veterinarian if Lucy should wait to be dewormed until the other medication is finished. Please feel free to post any additional questions.

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! For 24-48 hours after her vaccines, she may be tired or sore in the area where the vaccines were given. If you notice shes lethargic, vomiting, or having diarrhea, I would contact the vet that gave the vaccines. The dewormer will kill any intestinal parasites she may have. You may see worms pass in her feces. This is normal. You and your family can be around her. I would recommend cleaning up her stools right away, and washing your hands before eating. Kisses to Lucy!

I have never seen this as a side effect of the Profender but it is safe for cats to lick, as this has been tested by the company and is a common issue. If these symptoms continue, I'd be concerned she is having a seizure or some other issue, or an atypical allergic reaction to the medication, and consider taking her in for an exam.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Maisie. It may be she is feeling nauseous. Nausea can be a side effect. I'd keep an eye on her for now. If this behavior doesn't subside in 24 hours, then I'd have her checked out by a vet to be safe. I hope this helps!

Thank you for visiting Petco Pet Education Center, formerly Petcoach. What you describe definitely sounds like tapeworms. I am sorry to hear that Toby sounds like he is having an adverse reaction to the tapeworm medicaiton. This sounds serious. I would highly recommend taking Toby in to your vet to have him treated for an adverse reaction, which includes fluids for flush out his system and and symptomatic treatment. It’s best to take him in right away if possible. I hope that your pet Toby is able to make a full and speedy recovery. Best wishes and take care.
