Should my old dog with tapeworms get a full or half praziquantel dose?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 13 years and 10 months old | 45 lbs

My 14 year old pit bull mix has been having seizures on and off since May. She is definitely weakened, and getting near the end, but still has great appetite and is happy. Fleas (now under control) have led to tapeworms. I bought praziquantel tablets to give her, but concerned about her fragile state. She is 45 lbs. Should I give her half a dose? Will that work?

There are no warnings with praziquantel and dogs who have seizures, but I would check with your vet first to be safe before giving it to Nikki. If your vet says it's ok, then give her the whole dose as half a dose won't work. I hope this helps!

Is 34mg praziquantel twice a day too much for my 7lb chihuahua?

Praziquantel is typically given as a single dose. It may need to be repeated in 2 weeks. According to package information, one 34mg tablet is the dose given to dogs between 6 and 10 pounds. You will need to confirm this with your veterinarian though. Legally, we are prohibited from telling you to administer any medication to your pet in the absence of a physical exam.

My puppy's tapeworm medicine isn't working. What should I do next?

Hello. There have been some reports of drug resistance with tapeworms. I would talk to your vet about either upping the dose of the praziquantel or trying an alternate drug called epsiprantal. And make sure your vet sees a stool sample containing the tapeworm segments just to make sure there is not something else going on. Thanks for using Petco Pet Education Center, formerly Petcoach.

My puppy is scooting. Can I safely give another tapeworm dose?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Maeve. Praziquantel is a pretty safe drug and if you aren't sure she ate it, you can give her another dose now. Just make sure she does eat it. I hope this helps!

My cat's praziquantel crumbles. Is a slightly higher dose safe?

Praziquantel has a very high margin of safety, so it would be perfectly fine to go a bit high on young, healthy cat. Reactions can happen with any drug even at normal doses, so if he seems off afterwards, definitely take him in for evaluation, but I would be very comfortable with you giving half a tablet.

My dog only took half the dewormer dose. When can I give more?

I would probably recommend waiting 3-7 days and give her a full dose instead, don't try mixing it with water as it becomes very bad to the taste this way, either mix it with food without breaking it or give it manually until swallowed.

How much Drontal Plus should I give my 7kg puppy for tapeworms?

Drontal is a very safe deworming tablet, so I would give Tofy one table. Doses of up to 10 times the recommended dose will usually only cause some nausea, so giving her a little bit extra will not likely result in any harm. I hope this helps!

How many Praziquantel tablets for my cat's tapeworms and how often?

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Cats should be treated with an initial dose (based on the label instructions) and then again after 3 weeks. DO NOT give multiple doses in a day. Cats get tapeworms by ingested fleas that are infected with the tapeworm larvae so be sure to get the fleas under control.
