My daughter misdiagnosed what type of worms her puppy has (she definitely has Tapeworms), so I purchased Evict and administered it two days ago. Now I need to give an over the counter Tape worm medication and wonder how much time, if any, is required between the two different wormers?

I can't give you an authoritative answer. Likely the most reliable information would come from the directions for the Evict and the tape worm medicine or their website. The packaging may also have a help line number.

I have my dogs on Heartgard+ or Revolution year around which not only eliminate heart worms, but most other worms except the tape worms as well.

Thanks, Labman ~ I also would normally keep my dog/cat on the Flea & Tick OTC med year-round. However, my question pertained to a 9 week-old female Pug puppy! :)

I've made an appointment with the vet, to be on the safe side!
