Can I give my 6-week puppy an OTC dewormer after his Parvo shot?

It's best to wait until Jerry has recovered from the Parvo infection before giving the deworming tablet. If you give it now, she may vomit the medication and it will ultimately be ineffective. Worms often don't cause that many problems, so she would likely be fine to wait a few days while she recovers. However, it's best that you ask your vet doctor there about this. They will know her current condition better and be able to advise better. I hope that helps and Jerry gets better soon.

No, it won't mess up the visit. Let your veterinarian know you dewormed her today. Bring the package with you so he or she knows what was given. The deworming will likely need to be repeated at 2 week intervals over the next 8 weeks.

First of all regarding the worms and fleas, a food quality treatment for worms and for fleas will get rid of both within 24 hours, so make sure you use a high quality product. she is too young to get her parvo (and other) shot, you need to wait until she is 8 weeks old. she then will need 2-3 shots 2-4 weeks apart t o complete the vaccination course.

If Pixie is eating and drinking properly without vomitng and has no more diarrhea then you can worm her about a week after the last diarrhea. I would still wait a few weeks before vaccination as you want a fully recovered immune system in order to get a perfect immune response. So give it 2 weeks or so.

Looks like roundworms. There are many OTC dewormers that should work just fine. You can look for one that contains Pyrantel. It is still a good idea to have a vet diagnose what worms or other intestinal parasites are present. And Cujo will need re-treatment in 3 weeks to kill adults that hatch from eggs in the intestines right now.

Yes, a dog can have parvo and worms at the same time. Parvo is life threatening and often deadly with no cure, so the treatment focus would be exclusively on symptomatic treatment for that instead of the worms. Deworming treatments can cause vomiting and diarrhea, and it would not be wise to give a dog who is already vomiting and experiencing diarrhea a drug that could potentially cause more of that. If the dog does recover from parvo virus, as it is frequently fatal, then he can be treated for worms.

No. The over the counter medications are impossible to dose for a 1.5# dog. You will overdose her. Not only that but coccidia is a protozoan parasite and many over the counter medications do not treat this. I suggest you just use a probiotic for now. https://www.ebay.com/i/253095406158?chn=ps Hope this helps. Best wishes.
